Privacy Policy

We collect only what we need to run the service:

• Account information: your email address, display name and profile picture, and the sign-in method you use (email and password, Sign in with Apple or Google Sign-In). Passwords are handled by Firebase Authentication; we never see them.
• Your conversations: the messages you send to companions, the replies they generate, and images you attach to a message.
• Voice: when you use voice chat, audio from your microphone is streamed to our servers only while you are in a voice call, and is transcribed to text. The transcript is saved as a chat message. We do not store your voice recordings.
• Generated audio: voice replies spoken by a companion may be stored so you can replay them.
• Relationship data: bond level, relationship mode, streaks, and your language and voice settings for each companion.
• Purchases: your subscription status, coin balance and purchase history. Payments are processed by Apple or Google; we never receive your card details.
• Reports: the content you report, the reason you chose, and your app version and platform.
• Technical data: server logs, which include your IP address, device platform, app version, request times and error reports, used to keep the service secure and working.

We do not sell your personal data, we do not use it for advertising, and we do not track you across other companies' apps or websites.

• To provide the service: generate companion replies, remember earlier conversations, speak replies aloud, and transcribe your voice.
• To manage your account, subscription and coins, and to enforce plan limits.
• To keep the service safe: review reports, act on content that breaks our Community Guidelines, and prevent abuse and fraud.
• To fix problems and improve the service.
• To send you service emails, such as email verification.

We share data only with service providers that process it on our behalf to run ZeroWeight, and only what each one needs:

• Google Cloud and Firebase: hosting, databases, file storage and sign-in.
• AI model providers (such as xAI, OpenAI and DeepSeek): the text of a conversation is sent to generate the companion's reply.
• Google (Gemini) and OpenAI: your voice audio is sent to transcribe it to text.
• Cartesia and MiniMax: the text of a reply is sent to turn it into speech.
• Apple, Google and RevenueCat: to process and verify in-app purchases.
• Resend: to deliver service emails.
• Authorities, when the law requires it or when it is needed to protect someone's safety.

We keep your account information and conversations for as long as your account exists, so that your companions can remember you. Server logs are kept for a limited time for security and troubleshooting. Reports are kept as long as needed to handle them and to protect the community. Purchase records may be kept longer where tax or accounting law requires it.

Depending on where you live, you may have further rights, such as to object to or restrict processing, or to complain to your local data protection authority.

• Delete your account: in the app, go to Settings → Danger Zone → Delete Account. This deletes your profile and your sign-in. To have every remaining piece of data linked to your account (including conversations, images and generated audio) erased, email us and we will do it within 30 days.
• Access or correct your data: you can change your name, email, password and profile picture in Settings, or email us for a copy of your data.
• Microphone and camera: these are used only when you start a voice call or take a photo, and you can turn them off at any time in your device settings.
• Subscriptions: cancel at any time in your App Store or Google Play account settings.

Data is encrypted in transit, access to it is restricted to the people and systems that need it, and we use industry-standard security measures. No system is perfectly secure, so we cannot guarantee absolute security.

ZeroWeight is not intended for children under 13, and we do not knowingly collect their personal data. If you believe a child has given us personal data, contact us and we will delete it.

Our servers and service providers may be located outside your country, including in Singapore and the United States. We take steps so that your data stays protected wherever it is processed.

If we change this policy, we will update this page and its effective date, and tell you in the app or by email when the change is significant.
