Privacy Policy

Last updated: March 30, 2026

Speji ("we", "us", or "our") is a software project operated by an individual developer based in France. This Privacy Policy explains how we collect, use, share, and protect your personal data when you use the Speji mobile application (the "App") and the website at speji.com (the "Site"). It also describes your rights under the General Data Protection Regulation (GDPR) and applicable French law.

By downloading, installing, or using Speji, you acknowledge that you have read and understood this Privacy Policy.

1. Who We Are (Data Controller)

The data controller responsible for your personal data is:

• Name: Speji
• Contact: support@speji.com
• Country of operation: France

As the data controller, we are responsible for determining the purposes and means of processing your personal data.

2. Information We Collect

2.1 Account Information

When you create a Speji account, we collect:

• Email address and display name — provided at sign-up or retrieved from Google if you use Sign in with Google.
• Password (if using email/password sign-up) — stored as a secure hash by our authentication provider; we never see it in plaintext.
• Google profile information — name and email, obtained via Google OAuth only if you choose to sign in with Google.
• Profile picture — if you choose to set one.

2.2 Audio Data

Speji's core function is real-time audio capture, transcription, and translation. By default:

• Audio captured by your microphone is streamed in real-time to our backend server over an encrypted connection and immediately forwarded to our transcription provider (AssemblyAI).
• Audio is processed in real-time and not stored on our servers — it is discarded immediately after transcription.
• Transcription and translation results are held temporarily in your device's memory for display in the overlay, and are cleared automatically when you stop the session. They are never stored on our servers unless you actively enable the History feature (see below).

History Feature (future): We plan to offer an optional session history feature that would allow you to save your transcription and translation results on our servers. This feature will only activate at your explicit request. When it is available, you will be informed and asked for clear, specific consent before any transcript data is stored server-side. You will always be able to delete your saved history.

2.3 Usage & Billing Data

To manage your subscription and enforce plan limits, we store:

• Session duration — start time, billing heartbeat timestamps, and total minutes used per session.
• Minutes consumed — total usage against your monthly allocation or credit balance.
• Subscription tier — Free or paid tier name, subscription status, and renewal date.
• Credit balance — the number of prepaid minutes remaining if you have purchased credit packs.
• Usage session logs — used for billing accuracy, dispute resolution, and service improvement. These are retained for as long as your account is active, plus 12 months.

2.4 Advertising Identifier

If you use the Free tier, we display ads through Google AdMob. To do this, the App requests access to your device's Advertising ID (Google Ad ID). This identifier is used by Google to serve personalised or non-personalised advertisements. We do not link the Advertising ID to any personally identifiable account information on our end.

2.5 Technical & Device Data

Our backend and third-party services may collect standard technical data including:

• Device type, manufacturer, and operating system version
• App version
• IP address (used for security, fraud prevention, and geo-routing)
• WebSocket connection identifiers (transient, not permanently stored)

2.6 Crash & Error Reports

To maintain and improve the quality of the App, we automatically collect crash and error reports when the App encounters an unexpected failure. These reports may include:

• Error type, error message, and stack trace (technical code paths)
• Thread name and session identifier
• App version, Android version, and device model
• Timestamp of the error

Crash reports do not contain audio data, transcription content, translation content, or your account password. They are used solely for diagnosing and fixing bugs. Crash data is retained for up to 90 days and then automatically deleted.

2.7 Analytics Events

We collect anonymised, aggregated analytics events to understand how users interact with the App and to improve the service. These events include:

• App opens, session starts and ends, mode and language selections
• Feature usage patterns (e.g., which features are used most)
• Upgrade views and completions

Analytics events are stripped of personally identifiable information (email, name, phone, password, and token fields are automatically removed before storage). Events are associated with your user ID solely for aggregated analysis and are never used for profiling or advertising. Analytics data is automatically purged after 90 days.

2.8 Website Analytics

Our website (speji.com) uses the following analytics tools:

• Plausible Analytics — a privacy-focused, self-hosted analytics tool that does not use cookies, does not collect personal data, and is fully GDPR-compliant without requiring consent.
• Microsoft Clarity — used for heatmaps and session replays to understand how visitors interact with website pages. Clarity may process IP addresses and user interaction data. See Microsoft's Privacy Statement for details.

3. How We Use Your Information

We use the data we collect for the following purposes:

• Providing the service: Processing audio, returning transcriptions and translations, and displaying them as an overlay on your device.
• Account management: Creating and managing your account, authenticating you, and allowing you to manage your profile and settings.
• Billing & subscription management: Tracking your minute usage, enforcing plan limits, managing credit balances, processing payments via Google Play and RevenueCat, and handling refund requests.
• Advertising: For Free tier users, showing ads via Google AdMob to fund the service.
• Service communications: Sending account-related emails (verification, password reset, important policy updates). We do not send marketing emails without your consent.
• Security & fraud prevention: Monitoring for abuse, enforcing our Terms of Service, and protecting the integrity of the service.
• Crash diagnosis & bug fixes: Using crash and error reports to identify, diagnose, and resolve technical issues in the App.
• Service improvement: Analysing aggregated usage metrics and analytics events (e.g., language pairs most used, session durations, feature adoption) to improve performance and features. This analysis does not identify you personally.

4. Legal Basis for Processing (GDPR)

For users in the European Economic Area (EEA), our legal basis for processing your personal data is:

• Performance of a contract (Art. 6(1)(b)): Processing account data, audio, and billing data is necessary to provide the service you signed up for.
• Legitimate interests (Art. 6(1)(f)): Processing technical data, crash reports, and analytics events for security, fraud prevention, bug fixing, and service improvement, where our interests are not overridden by yours.
• Legal obligation (Art. 6(1)(c)): Retaining billing records as required by applicable law.
• Consent (Art. 6(1)(a)): For optional features such as the History feature (server-side transcript storage) and personalised advertising via AdMob, where required.

5. Third-Party Services & Data Processors

We rely on the following third-party services to operate Speji. When your data is shared with them, it is solely for providing the service to you and under strict data processing terms.

We do not sell, rent, or trade your personal data with any third party for their own marketing purposes. Data is only shared with the processors listed above as strictly necessary to provide the service.

6. International Data Transfers

Some of our third-party processors are located in the United States (AssemblyAI, Microsoft Azure, RevenueCat). When we transfer your data outside the European Economic Area, we rely on appropriate safeguards, including:

• Standard Contractual Clauses (SCCs) approved by the European Commission, or
• Adequacy decisions where applicable.

By using Speji, you acknowledge that your data may be transferred to and processed in countries outside the EEA.

7. Data Retention

• Account data: Retained for the lifetime of your account. Deleted within 30 days of account deletion upon request.

• Transcript history (future feature): Retained until you delete it or request deletion of your account.

8. Data Security

We take the security of your data seriously and implement the following measures:

• Encryption in transit: All communication between the App and our servers is encrypted using TLS (HTTPS/WSS).
• Authentication: All API access is authenticated via JWT tokens issued by Supabase. Unauthenticated connections are rejected.
• Row Level Security (RLS): Our database enforces RLS policies ensuring users can only access their own data.
• No audio storage: Audio is never written to disk on our servers.
• Access controls: Backend services operate with the minimum permissions required.
• PII stripping: Analytics events are automatically stripped of personally identifiable fields (email, name, phone, password, token) before storage.

However, no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your data, we cannot guarantee its absolute security.

9. Children's Privacy

Speji is not intended for use by persons under the age of 16. We do not knowingly collect personal data from children under 16. If you are a parent or guardian and believe your child has provided us with personal data, please contact us immediately at support@speji.com and we will delete that information promptly.

Terms of Service

Last updated: March 30, 2026

These Terms of Service ("Terms") govern your use of the Speji mobile application and related services (collectively, the "Service") operated by Speji ("we", "us", or "our"). By downloading, installing, or using Speji, you agree to be bound by these Terms. If you do not agree, please do not use the Service.

1. Description of Service

Speji is a real-time audio transcription and translation overlay application for Android. It captures audio from your device, sends it to our backend for processing via third-party AI services, and displays the resulting text as a transparent subtitle overlay on your screen. The Service is provided "as is" and is subject to continuous improvement and change.

2. Eligibility

You must be at least 16 years old to use Speji. By using the Service, you represent and warrant that you meet this age requirement. If you are under 16, you must not use Speji without verifiable parental or guardian consent.

You represent that you have the legal capacity to enter into a binding agreement and that your use of the Service does not violate any applicable laws or regulations.

3. Account Registration

To use Speji, you must create an account using a valid email address and password, or via Google Sign-In. You are responsible for:

• Maintaining the confidentiality of your credentials.
• All activities that occur under your account.
• Notifying us immediately at support@speji.com of any unauthorized use of your account.

We reserve the right to suspend or terminate accounts that violate these Terms or that we believe have been compromised.

4. Subscription Tiers, Credits & Billing

4.1 Tiers

Speji offers a Free tier and one or more paid subscription tiers. Each tier comes with a defined monthly allocation of transcription/translation minutes and varying features (language support, ad-free experience, etc.). Current tier details are displayed in the App at the time of subscription.

4.2 How Minutes Are Billed

Minutes are charged based on your active session duration — the time between starting and stopping the transcription overlay. Billing is calculated using a heartbeat system that records usage approximately every 60 seconds during an active session.

Sessions ended unexpectedly (e.g., due to a network interruption, application crash, or server restart) will be automatically recovered and billed for the actual duration of the session, as accurately as technically possible.

4.3 Billing via Google Play & RevenueCat

Paid subscriptions and credit packs are purchased and managed through Google Play, with subscription lifecycle management handled by RevenueCat. Payments, billing cycles, and refunds processed through Google Play are subject to Google Play's Terms of Service. We have no control over and are not responsible for payment processing by Google Play.

4.4 Billing Accuracy & Calculation Errors

We make every reasonable effort to bill you accurately. However, the Service relies on complex real-time systems involving network communication, server-side processing, and heartbeat-based metering. Minor calculation discrepancies may occur due to factors including but not limited to:

• Network latency or temporary connectivity losses
• Server-side processing delays or restarts
• Application crashes or unexpected termination
• Clock synchronisation differences between your device and our servers
• Rounding in minute calculations

If you believe you have been over-billed due to a technical error:

• The maximum discrepancy we consider eligible for correction is 2 minutes per session.
• Contact us as soon as possible at support@speji.com with your account email and the approximate date and time of the session in question.
• Upon verification, we will refund the incorrectly deducted minutes directly to your account's minute balance (not as a monetary refund, unless required by applicable law).

We are not able to offer refunds for minutes used correctly in accordance with the billing model described above. Minor variations in billing (within the 2-minute threshold) are an inherent characteristic of real-time metered services and do not constitute a defect or breach of these Terms.

4.5 Credit Packs (Prepaid Minutes)

In addition to subscription plans, Speji offers credit packs — one-time purchases of prepaid transcription/translation minutes. Credits:

• Do not expire and remain in your account until used.
• Are consumed after your monthly subscription minutes are exhausted (subscription minutes are always used first).
• Are non-transferable between accounts.
• Are subject to the same billing accuracy provisions described in section 4.4.

5. Free Tier & Advertising

The Free tier is funded by advertisements displayed within the App, served by Google AdMob. By using the Free tier, you consent to the display of advertisements.

We are not responsible for the content, accuracy, legality, or safety of any advertisement. Advertisements are served by Google and are governed by Google's own advertising policies. We do not endorse any products or services advertised. Any issues arising from advertiser content should be addressed directly to Google.

You can remove advertising by subscribing to a paid tier.

6. User Responsibilities & Prohibited Uses

You are solely responsible for how you use Speji and for all audio content you process through the Service. By using Speji, you agree not to:

• Record or transcribe private conversations without consent. You must have the legal right to record and transcribe any audio you process through Speji. Recording private conversations without the knowledge or consent of all parties may be illegal in your jurisdiction.
• Process or redistribute copyrighted content in violation of applicable copyright law (e.g., transcribing copyrighted films, shows, or music for redistribution).
• Use the Service for any illegal, harmful, abusive, defamatory, or fraudulent purpose.
• Attempt to reverse-engineer, hack, disrupt, or otherwise interfere with the Service or its infrastructure.
• Use automated scripts or bots to consume the Service beyond your subscription tier limits.
• Resell, sublicense, or share access to the Service without our prior written consent.
• Exploit known bugs or vulnerabilities to gain unfair advantage, including but not limited to circumventing billing, artificially inflating minute balances, or bypassing plan restrictions.

Enforcement: We do not actively monitor the audio content you process. The Service is a pass-through tool. However, if we receive a credible report of misuse, we reserve the right to investigate and, if the violation is confirmed, immediately suspend or permanently terminate your account, with forfeiture of any remaining subscription time or credit balance, without refund.

7. Service Availability, Crashes & Errors

Speji is provided on an "as available" basis. While we strive to maintain high availability, we do not guarantee that the Service will be uninterrupted, error-free, or available at all times. You acknowledge and accept that:

• The App may crash, freeze, or terminate unexpectedly due to device incompatibilities, operating system issues, memory constraints, network conditions, or software bugs.
• The backend servers may experience downtime for maintenance, upgrades, or due to unforeseen technical failures.
• Real-time features (transcription, translation, overlay rendering) may be temporarily degraded or unavailable due to third-party service outages (AssemblyAI, Microsoft Azure, etc.), network latency, or server load.
• Session recovery after a crash or disconnection is performed on a best-effort basis. We cannot guarantee that all session data will be recovered or that billing will be perfectly accurate in such cases.

We are not liable for any loss, inconvenience, or damage arising from service interruptions, crashes, or errors. We actively monitor for issues and work to resolve them as quickly as possible, but disruptions are an inherent risk of any software service.

8. Refund & Remedies Policy

8.1 General Principle

Subscriptions and credit packs are purchased through Google Play. Refund requests for monetary payments must be directed to Google Play in accordance with their refund policy. We do not process monetary refunds directly.

8.2 Service Issues & Goodwill Remedies

If you experience a verified technical issue that causes you to lose minutes or prevents you from using the Service as intended, we will work with you to resolve the problem. Our remedies may include:

• Minute credits: Adding complimentary minutes to your account balance to compensate for lost usage due to a verified bug or outage.
• Issue resolution: Deploying a fix for the technical issue as quickly as reasonably possible.

Goodwill remedies are provided at our sole discretion and are not guaranteed. They do not constitute an admission of liability. The scope of any remedy will be proportional to the impact of the issue.

8.3 What Does Not Qualify for a Remedy

The following situations do not qualify for refunds or minute credits:

• Dissatisfaction with transcription or translation quality (see section 9).
• Minutes consumed during normal use of the Service.
• Minor billing discrepancies within the 2-minute threshold described in section 4.4.
• Issues caused by your device, network, or third-party software.
• Failure to cancel a subscription before the renewal date.
• Changes in pricing, features, or supported languages.

8.4 Subscription Cancellation

You may cancel your subscription at any time through Google Play. Upon cancellation:

• You will retain access to your paid tier for the remainder of the current billing period.
• Your plan will revert to the Free tier at the end of the billing period.
• Unused monthly subscription minutes do not carry over and are forfeited.
• Any remaining credit pack minutes will be preserved and remain usable.

8.5 Full Refund Eligibility

Full monetary refunds (processed via Google Play) are only considered in exceptional circumstances, including but not limited to:

• A major, sustained service outage that renders the App completely unusable for an extended period (more than 72 continuous hours).
• A critical bug that permanently prevents you from accessing your account or using core functionality, and that we are unable to resolve within a reasonable timeframe.
• Accidental or unauthorized purchases, subject to Google Play's refund policy.

In all cases, refund eligibility is determined by Google Play's refund policies. We will cooperate with Google Play on legitimate refund requests and may provide supporting information when appropriate.

9. Transcription & Translation Accuracy Disclaimer

Speji uses third-party AI services for transcription (AssemblyAI) and translation (Microsoft Azure Translator). These are automated machine-learning systems, not human translators or transcribers. The results are generated automatically and may contain errors, omissions, mistranslations, or inaccuracies.

Transcription and translation quality depends on numerous factors outside our control, including but not limited to:

• Audio quality, volume level, and background noise
• Speaker accent, dialect, speech speed, and clarity
• Technical vocabulary, slang, idioms, and proper nouns
• The current state and limitations of the underlying AI models
• Network conditions affecting real-time data transmission
• Language pair complexity (some pairs are inherently less accurate than others)

We make absolutely no warranty, express or implied, regarding the accuracy, completeness, reliability, or fitness for any particular purpose of any transcription or translation produced by the Service.

You expressly acknowledge and agree that:

• Speji outputs should never be relied upon for medical, legal, financial, safety-critical, or professional contexts where accuracy is essential.
• You are solely responsible for verifying the accuracy of any output before using it for any important purpose.
• Errors in transcription or translation are inherent to the technology and do not constitute a defect in the Service or a breach of these Terms.
• We are not liable for any decisions made, actions taken, misunderstandings, or consequences of any kind arising from reliance on inaccurate, incomplete, or incorrect transcriptions or translations.

We are not responsible for the audio content you choose to process through the Service. You bear sole responsibility for the legality and appropriateness of the audio input and any use you make of the output.

10. Intellectual Property

All rights, title, and interest in the Speji application, including its design, code, trademarks, and brand assets, are owned by Speji. You are granted a limited, non-exclusive, non-transferable, revocable licence to use the App on your personal Android device solely for personal, non-commercial purposes in accordance with these Terms.

Nothing in these Terms grants you any right to copy, modify, distribute, sell, or create derivative works of the App.

11. Limitation of Liability

To the fullest extent permitted by applicable law:

• The Service is provided "as is" and "as available", without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, or accuracy of output.
• We do not warrant that the Service will be uninterrupted, error-free, free from harmful components, or that defects will be corrected within any particular timeframe.
• We expressly disclaim all liability for errors, inaccuracies, or omissions in transcriptions, translations, or any other output produced by the Service.
• We expressly disclaim all liability for application crashes, data loss during sessions, or service interruptions, regardless of cause.
• In no event shall Speji be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the Service — including but not limited to loss of data, loss of revenue, loss of goodwill, loss of business opportunity, or emotional distress — even if advised of the possibility of such damages.
• Our total aggregate liability to you for any claim arising out of or relating to these Terms or the Service shall not exceed the total amount paid by you for the Service in the three (3) months preceding the event giving rise to the claim, or €50 (fifty euros), whichever is lower.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. In such cases, the above limitations apply to the maximum extent permitted by law.

12. Indemnification

You agree to indemnify, defend, and hold harmless Speji, its developer(s), and any affiliates from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising from or related to:

• Your use of the Service or any violation of these Terms.
• Any audio content you process through the Service, including claims of copyright infringement, privacy violations, or defamation.
• Your reliance on transcription or translation outputs for any purpose.
• Any action or inaction based on the Service's output.

13. Force Majeure

We shall not be liable for any failure or delay in performing our obligations under these Terms if such failure or delay results from circumstances beyond our reasonable control, including but not limited to: natural disasters, pandemics, war, terrorism, government actions, power outages, internet or telecommunications failures, third-party service outages (including AssemblyAI, Microsoft Azure, Google Play, Supabase, or RevenueCat), cyberattacks, or labour disputes.

14. Service Modifications & Termination

We reserve the right to:

• Modify, suspend, or discontinue any part of the Service at any time, with or without notice, for reasons including technical constraints, commercial decisions, or regulatory requirements. This includes changes to supported languages, features, tier allocations, or pricing.
• Update these Terms at any time. Material changes will be notified via the App or email. Your continued use of the Service after any change constitutes acceptance of the updated Terms.
• Terminate your access to the Service if you violate these Terms or for any other reason at our sole discretion.

Upon termination, your right to use the Service ceases immediately. Provisions that by their nature should survive termination (including liability limitations, indemnification, intellectual property, and dispute resolution) shall do so.

15. Governing Law & Dispute Resolution

These Terms are governed by and construed in accordance with the laws of France, without regard to its conflict of law provisions.

Any dispute arising out of or relating to these Terms or the Service will be subject to the exclusive jurisdiction of the competent courts of France.

Before initiating formal proceedings, we encourage you to first contact us at support@speji.com to attempt to resolve the issue informally. We commit to responding to disputes within 15 business days.

If you are an EU consumer, you may also use the EU Online Dispute Resolution (ODR) platform.

16. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions shall remain in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable while preserving its original intent.

17. Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Speji regarding your use of the Service. They supersede all prior agreements, communications, and understandings, whether written or oral, relating to the subject matter herein.
