Privacy Policy
This policy covers every app published by Sinfy AI on the App Store, and the website sinfyai.com. It is written to be read, not skimmed. If an app needs something beyond what is described here, that app has its own section at the bottom of this page.
Who we are
Sinfy AI ("we", "us") is a software company based in California, United States. We build apps for iPhone and iPad. You can reach us at hello@sinfyai.com.
The short version
- No accounts. Our apps do not require you to create an account or sign in, unless an app-specific section below says otherwise.
- Your content stays on your device. What you create in an app is stored on your device, and in your iCloud if you turn that on. We cannot see it.
- No selling, no ad networks. We do not sell personal information and we do not run third-party advertising in our apps.
- Purchases go through Apple. We never see your payment card. Apple gives us only what is needed to unlock what you bought.
What we collect
Information you give us. If you e-mail us for support, we keep that e-mail and your address so we can reply and follow up.
Purchase information from Apple. When you buy a subscription or an in-app purchase, Apple processes the payment and sends us a receipt record: the product bought, the date, and whether it is active. It does not include your name, e-mail, or card details.
Crash and performance reports. If you have opted in to share diagnostics with app developers in your iPhone settings, Apple sends us anonymous crash reports and performance data. We use them to fix bugs. They do not identify you.
Nothing else by default. Our apps do not track you across other apps or websites, and do not collect your location, contacts, photos, or microphone data unless a feature you turn on plainly needs it, in which case iOS asks for your permission first and the data is used only for that feature on your device.
Features that use AI
Some of our apps use AI models to do their work. Where the model runs on your device, nothing leaves your phone. Where a feature sends text, audio, or images to a cloud model to produce a result, the app tells you before you first use that feature, sends only what the feature needs, and does not use your content to train models. The providers we work with are bound by contracts that limit them to processing the request and returning the answer. App-specific sections below name the providers for each app.
How we use information
- To make the app work and unlock what you paid for.
- To answer your support requests.
- To find and fix crashes.
- To comply with the law.
Sharing
We share information only with service providers that help us run the apps (Apple for purchases and diagnostics, and the AI providers named in app-specific sections), only for the purposes above, and only under contracts that prohibit them from using it for anything else. We may also disclose information if the law requires it, or to protect the rights and safety of our users or ourselves. We do not sell or "share" personal information as those words are defined by California law.
Retention
Support e-mails are kept for up to two years so we can reference past issues. Purchase records are kept for as long as your purchase or subscription can be restored, plus what tax and accounting law requires. Crash reports are kept for 90 days.
Your choices and rights
You can delete an app and everything it stored on your device at any time. You can manage or cancel subscriptions in your Apple ID settings. You can turn diagnostics sharing off in Settings → Privacy & Security → Analytics & Improvements.
California residents have the right under the California Consumer Privacy Act to know what personal information we hold about you, to ask us to delete it, to correct it, and to not be discriminated against for exercising these rights. Because we hold so little, most requests are answered by confirming that we hold nothing beyond what is described here. To make a request, e-mail hello@sinfyai.com from the address you used with us. We answer within 45 days. We do not sell or share personal information, so there is no opt-out to exercise. We do not use or disclose sensitive personal information for any purpose other than providing the app.
Residents of other US states with consumer privacy laws (including Colorado, Connecticut, Virginia, Utah, Texas, and Oregon) have similar rights of access, correction, and deletion, and can use the same address.
Children
Our apps are made for adults and are not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has given us personal information, e-mail us and we will delete it.
Security
The little data we hold is kept on access-controlled systems. Data in transit between our apps and any server is encrypted. No system is perfectly secure, and we will notify you as the law requires if a breach affects your information.
Changes
When we change this policy, we update the date at the top and, for material changes, tell you inside the app before the change takes effect. Earlier versions are available on request.

App-specific notes
None yet. When an app collects or processes anything beyond what is described above, it gets its own section here, named after the app, before it ships.
