Privacy Policy — Vaani

Effective date: 25 June 2026

Vaani ("the Service", "we", "us") is a text-to-speech assistant. You send it text or a document over WhatsApp (or Telegram), and it replies with a voice note that reads your content aloud. This policy explains what we collect, how we use it, and the choices you have. By messaging Vaani, you agree to this policy.

1. Information we collect

We keep data collection to the minimum needed to provide the Service.

Your identifier. When you message us, the messaging platform (WhatsApp or Telegram) gives us the identifier you contact us with — your WhatsApp phone number or Telegram user ID — and, where the platform provides it, your display name or username. We use this only to recognise you and store your preferences.
Message content you send (processed, not stored). The text of your messages and the text extracted from documents you upload are processed only to generate your voice note. We do not retain the content of your messages, your uploaded documents, or the generated audio after your request is fulfilled — they are handled in memory and discarded.
Your preferences. We store your voice/speech settings (chosen voice, speed, pitch, and whether conversational rewriting is enabled) so they persist between messages.

We do not collect your contacts or location, we do not use your data for advertising, and we never sell it.

2. How we use your information

recognise you and apply your saved voice preferences;
convert your text or document into a spoken voice note and send it back;
optionally improve the phrasing of your text for more natural speech when you have enabled "conversation mode";
operate, secure, and debug the Service.

3. Third-party services (sub-processors)

To deliver your voice note, your text is sent to the following providers strictly for processing on our behalf. We share only the text needed to perform the task.

Provider	Purpose	What is shared
WhatsApp / Meta	Message delivery (the platform you contact us on)	Your messages and our replies, per Meta's policies
Telegram	Message delivery (Telegram version of the Service)	Your messages and our replies, per Telegram's policies
Microsoft (Azure Neural / Edge TTS)	Text-to-speech synthesis	The text to be spoken
Google (Gemini)	Optional conversational rewrite — only when you enable conversation mode	The text to be rewritten
ElevenLabs	Optional alternative voice engine, where enabled	The text to be spoken
Cloudflare	Secure network delivery to our server	Standard request metadata (e.g. IP, headers)

These providers process data under their own privacy policies. We limit what we send them to the content required for the requested conversion.

4. Data storage and retention

Message and document content: not stored; processed transiently and discarded after your voice note is sent.
Generated audio: not stored.
Your identifier and preferences: stored on our self-managed database until you request deletion or the Service is discontinued.

5. Security

Data in transit is protected with encryption (HTTPS/TLS). Inbound platform requests are authenticated (e.g. signature verification on WhatsApp webhooks), and access to stored data is restricted to the operator. No method of transmission or storage is 100% secure, but we take reasonable measures to protect your information.

6. Your rights and choices

Stop using the Service at any time by no longer messaging it; you may also block the number on WhatsApp.
Request deletion of your stored identifier and preferences by emailing contact@akhilsingh.in. We will delete them within a reasonable period.
Access or correction: contact us at the address above with any request about your data.

7. Children's privacy

The Service is not directed to children under the age required by your local law (e.g. 13, or 16 in parts of the EEA), and we do not knowingly collect their data. If you believe a child has used the Service, contact us and we will delete the associated data.

8. International users

The Service may process and store data on infrastructure located in different countries than yours. By using the Service you consent to such processing.

9. Changes to this policy

We may update this policy from time to time. The "Effective date" above reflects the latest version. Continued use of the Service after changes constitutes acceptance.
