Privacy Policy

The short version

There is no account and no sign-up. Your conversations are stored on your own device. To generate a reply we send the text of that conversation to our server, which passes it to Google's Gemini API and streams the answer back. We do not store the content of your conversations on our server, and we do not sell anything to anyone.

Who we are

YourOwnWaifu is an independent project operated by a single developer. Contact: the contact page.

What we collect

An anonymous install identifier

When you first open the app it generates a random identifier (a UUID) and stores it on your device. It is not derived from your name, your phone, your email or any hardware ID, and it is not linked to any account. We use it, together with your IP address, only to count requests so that one install cannot exhaust the service for everybody else. You can erase it at any time from Settings → Privacy → Delete all my data, which generates a fresh one.

Message content, while a reply is being generated

Your messages, the character's persona, and any relevant remembered facts are sent to our server so a reply can be produced. Our server forwards them to the Google Gemini API and streams the result back to you. We do not write this content to a database or a log file. Our server logs do record request metadata — IP address, install identifier, timestamp, and which model was used — which we need for rate limiting and for diagnosing failures.

Images you attach

If you send the companion a photo, that image is transmitted the same way as a message and is subject to the same handling. It is not retained by us after the reply is produced.

Voice

Speech recognition is performed by your device's own speech service (Google or Apple, depending on your phone), under their privacy policy, not ours — your audio does not pass through our server. For the companion's voice, the text of her reply is sent to Microsoft's Edge text-to-speech service to be turned into audio.

Reports you send

If you report a reply from inside the app, we receive the text of that reply plus your app version, device platform and install identifier, so we can investigate. This is sent only when you choose to report something.

What we do not collect

No name, email address, phone number, contacts, precise location, advertising identifier or payment information. There are no third-party advertising or analytics SDKs in the app.

What stays on your device

Your conversation history, the companion's long-term memories, your chosen character, and all of your settings are stored in the app's private storage on your phone. They are not backed up to us and we cannot read them. Uninstalling the app deletes them.

Who else processes your data

• Google (Gemini API) — generates the companion's replies and the images she draws.
• Microsoft (Edge text-to-speech) — turns her replies into speech.
• Google or Apple speech recognition — converts your voice to text on your device.

Each of these providers handles the data it receives under its own privacy policy. We do not share your data with anyone else, and we never sell it.

How long we keep things

Request metadata used for rate limiting is kept for as long as the counter is active and is reset periodically. Reports you send are kept until the issue is resolved. Conversation content is not retained at all.

Deleting your data

Because we hold no account, everything that identifies you is under your control. Settings → Privacy → Delete all my data erases every conversation and memory on the device and replaces your install identifier, after which nothing connects your future requests to your past ones. Uninstalling the app has the same effect on device data. If you want a report you sent us removed, use the contact page and include the approximate date.

Children

This app is not intended for children. You must be at least 18 years old, or the age of majority where you live, to use it. We do not knowingly collect data from children.

Your rights

If you are in the EEA or the UK, the GDPR gives you rights of access, rectification, erasure, restriction, objection and portability. Our lawful basis for processing the limited data described above is legitimate interest in operating and protecting the service. Because we deliberately hold almost nothing that identifies you, an access request will usually return only request metadata tied to your install identifier — which you can find and reset in the app. Contact us through the contact page to exercise these rights.

Changes

If this policy changes materially we will update the date at the top of this page and note the change in the app's release notes.
