Privacy Policy

Last updated: October 17, 2026

Timer AI ("we", "our", or "us") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.

Information We Collect

• Account data: When you sign in with Apple or Google, we receive your name and email address.
• Timers and sessions: Timers you create, sessions you complete, and notes you add. If you are signed in, these are stored on our server. If you are not, they stay on your device; the app also keeps a short record of finished sessions on your device to show your week and your streak.
• Voice recordings:If you use voice input or voice notes, audio is processed by OpenAI's API and immediately discarded — we do not store raw audio.
• Photos of written lists: If you photograph a written list, it is read on your deviceand only the recognised text is sent to us. If the handwriting is hard to read you may separately choose "Read with AI"; only then is that one photo sent to our server and on to OpenAI's API to be transcribed. We hold it in memory for the length of that request and never store it. This never happens automatically — you are asked each time.
• Usage data: Which sessions are opened, started and finished, which screens lead to a purchase, and whether creating a timer with AI worked. This is linked to a random identifier, or to your account ID if you are signed in — never to your email. It is processed by PostHog on servers in the European Union.
• Crash reports: If the app crashes, a technical report of the crash is sent the next time you open it, through PostHog, so we can fix it.
• Advertising measurement:The app includes the TikTok Business SDK to measure whether our TikTok ads lead to installs and purchases. Your device's advertising identifier is only shared if you allow tracking when iOS asks; you can change this at any time in Settings → Privacy & Security → Tracking.

On This Website

• No account needed: You can use timerai.online without signing up. We do not ask for your name or email.
• Analytics without cookies: We count page views, which sessions are opened, started and finished, when a Premium sheet or a QR code is shown, whether you allow notifications, and taps on the App Store buttons, using PostHog on servers in the European Union. The website sets no cookie and stores no identifier on your device: each visit gets a random identifier that is kept only in memory and is gone when you close or reload the page. If your browser sends a Do Not Track or Global Privacy Control signal, no analytics are sent at all.
• Kept on this device:Your timers and preferences on the website, such as your scene, your sound and a session in progress, are saved in your browser's local storage on this device, not on our servers. Apart from the analytics above, the only part of a session that leaves your browser is the text it speaks aloud, which is sent to be turned into speech. Clearing this site's data in your browser removes the rest.

How We Use Your Data

• To provide and sync your workout timers across sessions
• To generate AI-powered interval timers from your input
• To speak your session's cues and countdowns aloud
• To display your history, your week and your streak
• To send reminders, only if you turn notifications on
• To understand how the app is used, find crashes, and measure our ads

Third-Party Services

• OpenAI: Used for timer parsing, text-to-speech, and — only when you explicitly ask for it — reading a photographed list. OpenAI may retain API data for a limited period for abuse monitoring under their own policy. See OpenAI Privacy Policy.
• ElevenLabs: Generates some of the coach voices. Only the text to be spoken is sent. See ElevenLabs Privacy Policy.
• PostHog: Usage analytics and crash reports, hosted in the European Union. See PostHog Privacy Policy.
• TikTok: Advertising measurement through the TikTok Business SDK, as described above. See TikTok Privacy Policy.
• Apple Sign In / Google Sign In: Authentication only. We do not share your credentials.
• RevenueCat: Manages in-app purchases. See RevenueCat Privacy Policy.

Data Retention

Your data is stored as long as your account is active. You can delete your account and its data from Settings inside the app, or ask us to at support@timerai.online. Data kept only on your device is removed when you delete the app.

Children's Privacy

Timer AI is not directed to children under 13. We do not knowingly collect data from children under 13.
