Privacy Policy

Last updated: 14 October 2026 · Suftnet Limited

Tranquis ("we", "our", or "us") is operated by Suftnet Limited. This Privacy Policy explains how we collect, use, and protect your information when you use the Tranquis mobile application.

1. Information We Collect

We collect the following types of information:

Account information — your email address and display name when you register.
Translation content — text, voice recordings, and images you submit for translation. The original text and its translation are saved to your translation history so you can find them later; you can delete individual items or your whole history at any time in the app. Voice recordings and images themselves are not kept after the translation is complete.
Usage data — app features used, session length, and error logs, collected anonymously to improve the service.
Device information — device model, operating system version, and app version for debugging purposes.
Subscription and payment data — managed entirely by Apple (App Store) or Stripe. We do not receive or store your card details.

2. How We Use Your Information

To provide translation and interpretation services.
To manage your account and subscription.
To improve app performance and fix bugs.
To send transactional emails (e.g. subscription confirmations). We do not send marketing emails without your consent.

3. Translation Processing

Translation requests are sent securely to our backend servers and to OpenAI, our AI provider, which processes the text, audio and images you submit in order to produce translations, transcriptions and spoken audio. Voice recordings are transcribed in real time and are not stored on our servers after the translation is complete. Camera images are sent to our servers for text recognition and deleted immediately after the result is returned; only the recognised text and its translation are saved to your history.

4. Data Sharing

We do not sell your personal data. We share data only with:

Translation providers — OpenAI, to fulfil translation, transcription and text-to-speech requests (text, audio and image content).
Infrastructure providers — for hosting and analytics (e.g. Render, Sentry). These providers process data solely on our behalf.
Apple / Stripe — for payment processing under their own privacy policies.
Law enforcement — if required by applicable law.

5. Data Retention

We retain your account data for as long as your account is active. Translation history and phrasebook entries are kept until you delete them in the app, and are deleted automatically after 12 months. You may delete your account at any time from Settings in the app, or by contacting us at privacy@edquis.com, after which all personal data is deleted within 30 days.

6. Children's Privacy

Tranquis is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe we have collected data from a child, please contact us and we will delete it promptly.

7. Your Rights

Depending on your location, you may have rights to access, correct, or delete your personal data, or to object to or restrict certain processing. To exercise these rights, contact us at privacy@edquis.com.

8. Security

We use industry-standard encryption (TLS) for all data in transit. Access to user data is restricted to authorised personnel only.

9. Changes to This Policy

We may update this policy from time to time. We will notify you of material changes via in-app notification or email. Continued use of the app after changes constitutes acceptance of the updated policy.
