Privacy Policy
Let Talk is an iPhone app for voice calls, video calls and messages that are translated between languages. This policy explains what information Let Talk collects, why, who it is shared with, and how you can delete it. Let Talk is operated by [COMPANY LEGAL NAME] ("we", "us").
- We collect what we need to run your account, connect your calls and deliver your messages.
- To translate, your speech is converted to text, and that text is sent to Google Cloud Translation or OpenAI. Call audio and video are not recorded or stored.
- We do not sell your information, and we do not use it for advertising.
- You can delete your account and its data at any time in the app: Settings → Delete Account.
1. Information we collect
Information you give us
- Account details: your name, email address, phone number and password. If you sign in with Apple or Google, we receive the name and email address that service shares with us.
- Profile: your profile photo (optional), preferred language and gender. Gender is used only to choose a default translation voice, and you can change the voice at any time.
- Contacts you save in Let Talk: the names and phone numbers you add, and the Let Talk accounts you add by QR code.
- Messages: the text of messages you send and receive in Let Talk.
- Reports and blocks: users you block and reports you submit about other users or content.
Information created when you use the app
- Call records: who called whom, whether it was a voice or video call, when it started and ended, and its status (answered, missed, declined).
- Call connection data: technical data exchanged to connect a call, such as network addresses and connection parameters. It is kept only as long as needed to set up the call.
- Device push tokens: identifiers that let us notify your iPhone about incoming calls and messages.
Your phone's contacts (optional)
If you allow access to your contacts, Let Talk reads the phone numbers on your iPhone to show which of your contacts already use Let Talk. Phone numbers are converted to a one-way hash on your device before they are compared, and we do not upload or keep your address book. You can turn this off at any time in iOS Settings → Let Talk → Contacts.
Camera, microphone and speech recognition
Let Talk uses your microphone and camera only during calls, and the camera also to scan Let Talk QR codes. Live translation uses Apple's speech recognition to turn what you say into text. Depending on your device and language, Apple may process that audio on your iPhone or on Apple's servers, under Apple's Privacy Policy. Let Talk does not record or store your call audio or video.
2. How translation works
When you turn on translation, Let Talk asks for your consent first. After that:
- Your speech is converted to text by Apple's speech recognition, as described above.
- The text, or the text of a message you send, goes to our server, and from there to Google Cloud Translation or OpenAI to be translated and to detect its language.
- The translation comes back to the app. It is shown as subtitles and spoken aloud with a voice built into your iPhone.
Only the text to be translated is sent to these providers. Your name, phone number and email address are not sent to them. Translated call captions are not stored on our servers.
3. How we use information
- To create and secure your account and keep you signed in.
- To connect calls, deliver messages and send you call and message notifications.
- To translate your calls and messages when you ask us to.
- To show which of your contacts use Let Talk, and to let people add you by QR code.
- To act on reports, enforce our Terms of Service and keep the service safe.
- To fix problems and keep the service running.
We do not sell your personal information, we do not share it for cross-context behavioral advertising, and we do not use your messages or calls to train AI models.
4. Who we share information with
We share information only with the service providers that run parts of Let Talk for us, and only for that purpose:
| Provider | What it does | What it receives |
|---|---|---|
| Supabase | Database, sign-in, file storage and server functions | Your account, profile, contacts, messages, call records and push tokens |
| Google Cloud Translation | Translation and language detection | Text to be translated |
| OpenAI | Translation | Text to be translated |
| Cloudflare | Relays call audio and video when a direct connection isn't possible | Encrypted call streams, which it cannot read, and network addresses |
| Apple | Push notifications, speech recognition, Sign in with Apple and payments | Push tokens and notification content, speech audio as described above, and sign-in details |
| Sign in with Google (if you use it) | Sign-in details |
Each provider handles data under its own terms and privacy policy. OpenAI may keep API data for up to 30 days to monitor abuse and does not use it for training. We may also disclose information if the law requires it, to protect someone's safety, or as part of a merger or sale of the business, in which case this policy would continue to apply.
5. Calls and message security
Call audio and video travel directly between devices whenever possible, encrypted with DTLS-SRTP, the standard used by WebRTC. When a direct connection isn't possible, the encrypted streams pass through Cloudflare's relay servers. Messages and account data are encrypted in transit and stored with Supabase. Messages are not end-to-end encrypted, because they must be readable by our server so they can be translated.
6. How long we keep information
- Account, profile, contacts, messages and call records: until you delete them or delete your account.
- Call connection data: only as long as needed to set up the call.
- Reports: as long as needed to review them and keep the service safe.
- Backups: deleted data can remain in our database provider's backups for up to 30 days before it is overwritten.
7. Deleting your account
You can delete your account at any time in the app: Settings → Delete Account. This permanently deletes your login, your profile, your photo and other files, your saved contacts, your messages and call records, the blocks you've made, and your device push tokens. The deletion happens right away and can't be undone. Copies in backups are overwritten within 30 days.
If you can't open the app, email support@lettalkapp.com from the email address on your account, and we'll delete it within 30 days.
8. Your choices and rights
- You can update your profile, language and voice in Settings.
- You can turn off contacts, camera, microphone, speech recognition and notification access in iOS Settings.
- You can withdraw your consent to translation by turning translation off. Calls still work without it.
- Depending on where you live (for example, the EU, the UK or California), you may have the right to access, correct, delete or export your information, or to object to certain processing. To make a request, email support@lettalkapp.com. We will not treat you differently for using these rights.
9. Children
Let Talk is not intended for children under 13, or for anyone under the minimum age required by the laws where they live, and we do not knowingly collect their information. If you believe a child has created an account, contact us and we will delete it.
10. International users
Let Talk and its service providers may process information in the United States and other countries, which may have different data protection laws from yours. Where the law requires it, we rely on appropriate safeguards for these transfers.
11. Changes to this policy
If we make material changes to this policy, we'll update the date at the top and let you know in the app before the changes take effect.
