1The short version
Echo is an AI assistant. To answer you, it has to send what you ask to an AI model. This policy explains what that means for your data.
- Your conversations are never publicly accessible to others.
- Invisible Chat is never written to your history or stored on our servers.
- We do not sell your personal information.
- You can delete your account and its data at any time.
2What we collect
Account details.When you sign in with Apple, Google, or an email code, we store the identifier and email address needed to recognise you next time. If you use Apple’s private relay, we only ever see the relay address.
Conversations.Standard chats — your messages and Echo’s responses — are saved to your account so History works. Invisible Chat is the exception and is never persisted.
Files you attach. Photos and documents you upload are processed to answer your request. Generated images and sticker packs are stored so they remain available in your library.
Approximate location. Only if you grant permission, and only to answer location questions such as finding places nearby. You can revoke it at any time in iOS Settings; the rest of Echo keeps working.
Diagnostics. Basic technical logs — timestamps, error codes, coarse device and app version — used to keep the service running and to investigate faults.
3How we use it
We use the information above to:
- Answer your requests and generate the content you ask for.
- Keep your history and library available across sessions.
- Operate subscriptions and entitlements.
- Detect abuse, enforce usage limits, and keep Echo secure.
- Diagnose faults and improve reliability.
We do not sell your personal information, and we do not use the content of your conversations to advertise to you.
4AI model providers
Echo is an aggregator. To answer you, the content of your request — including any photo or document you attach — is sent to the AI provider behind the model you selected. Those providers process it under their own terms and privacy policies to return a response.
Which providers are involved depends on the models available in Echo at the time and which you choose. We use commercial API tiers, which generally do not train foundation models on submitted content, but the provider’s own policy governs their handling.
Invisible Chat still goes to a model provider in order to produce an answer. What it does is guarantee the exchange is not written to your Echo history or our database.
5Who else processes data
We share data with service providers that run Echo on our behalf, under contracts limiting them to that purpose:
- Cloud hosting and managed database providers.
- Authentication and account infrastructure.
- AI model providers, as described above.
- Apple, for subscription purchases and receipt validation.
We may also disclose information where required by law, or to protect the rights and safety of users and the public.
6How long we keep it
Conversations, generated images, and sticker packs are kept until you delete them or delete your account. Invisible Chat is never stored, so there is nothing to retain. Diagnostic logs are kept for a limited period and then discarded.
When you delete your account we remove your personal data from our production systems. Residual copies may persist briefly in encrypted backups before being overwritten on their normal cycle. See Delete your data for the exact steps and what each one removes.
7Your choices and rights
- Delete individual chats or images from History at any time.
- Use Invisible Chat when you would rather an exchange leave no trace.
- Revoke location or photo access in iOS Settings.
- Delete your account and its associated data from within the app.
Depending on where you live, you may also have rights to access, correct, export, or object to processing of your personal data. Email support@echo.plus and we will respond within the period required by applicable law.
8Children
Echo is not directed at children under 13, and we do not knowingly collect their personal information. If you believe a child has provided us data, contact us and we will delete it.
9International transfers
Echo is operated from, and uses providers located in, countries that may differ from where you live. Where required, we rely on appropriate safeguards for those transfers.
10Changes and contact
We will update this policy as Echo changes, and will give notice in the app or by email if a change is material.
Echo is the controller of the personal data described here. Questions or requests: email support@echo.plus or use the contact page. See also our Terms of Service.
