Privacy Policy

Last updated: March 10, 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.
• Subscription tier — Free or paid tier name, subscription status, and renewal date.
• 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)

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, 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.
• Service improvement: Analysing aggregated usage metrics (e.g., language pairs most used, session durations) 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 for security, fraud prevention, 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.
• Audio data: Not retained. Processed in real-time and discarded immediately.
• Billing & session data: Retained for the duration of your account plus 12 months for dispute resolution, then deleted.
• 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.

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.

Terms of Service

Last updated: March 10, 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 & 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 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 & Technical Over-Billing

We make every effort to bill you accurately. However, in rare cases, technical issues (such as network failures or system crashes) may cause the system to deduct more minutes than you actually used.

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.

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.

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, without refund.

7. Translation Accuracy & Content Disclaimer

Speji uses third-party AI services for transcription (AssemblyAI) and translation (Microsoft Azure Translator). The results are generated automatically and may contain errors, omissions, or inaccuracies. Transcription and translation quality depends on factors including audio quality, background noise, speaker accents, vocabulary, and the current state of the underlying AI models.

We make no warranty regarding the accuracy, completeness, or fitness for any purpose of any transcription or translation produced by the Service. You should not rely on Speji outputs for medical, legal, safety-critical, or professional contexts.

We continuously work to improve the quality of our service. Occasional errors are inherent to the technology. We are not liable for any decisions made, actions taken, or consequences arising from reliance on inaccurate 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.

8. 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.

9. 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, or non-infringement.
• We do not warrant that the Service will be uninterrupted, error-free, or free from harmful components.
• 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, or loss of goodwill — 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.

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.

10. 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.
• 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, intellectual property, and dispute resolution) shall do so.

11. 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.

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