Privacy policy
Effective September 27, 2026
The short version: nothing your phone senses ever leaves it. No camera, microphone or motion data is sent anywhere. There are no accounts, ads, analytics, trackers or cookies, and we never sell or share your data with anyone, for any reason.
- No data collected, sold or shared
- Camera, microphone and motion data never leave your phone
- No accounts or sign-up
- No ads
- No analytics or tracking
- No cookies
- License checked offline, on your phone
What the app uses, and what happens to it
- Motion sensor: readings are turned into a number, compared with your threshold, and discarded.
- Camera: each frame is compared with the one before it, inside the box you draw, and discarded. No photos or video are saved or sent.
- Microphone: sound is measured for loudness in pitch ranges and discarded. No audio is recorded or sent. In Sound (advanced) mode, the examples you record are saved as a sound fingerprint: numbers describing how loud each pitch range is over time, not audio.
- Counts, settings, saved setups, the timing log and your license key: saved in your browser's storage on your phone so they survive closing the page.
Your phone asks permission before the app can use the motion sensor, camera or microphone. You can turn any of these off at any time in your browser's or phone's settings.
What leaves your phone
The app's page blocks all network requests, so it has no way to send data anywhere. License keys are checked on your phone, offline. Things leave your phone only when you choose:
- Export CSV, Copy CSV and Export setups file: you choose where the file goes.
- Buying a license: after checkout, the thank-you page makes one request to our server with your checkout reference. The server asks Polar to confirm the payment and sends back your license key. If Polar has no name for the purchase, the page asks for one to put on the license and sends it with that request. We don't store that request.
- Feedback and support emails: open your email app. What you send is used only to reply to you and improve the app.
- Links: Buy license and Support development open Polar's checkout. Instructions open Google Drive. Those sites have their own privacy policies.
Payments
Purchases are handled by Polar, the merchant of record. Polar receives your name, email address, country and payment details to process the payment, send your receipt and handle sales tax. We can see your name, email and country in Polar's order records and use them only for support, refunds and tax records. We never see your card details. The name you enter at checkout is written into your license key and shown in the app as "Licensed to".
Hosting
The site is hosted on Netlify. When you load a page, Netlify's servers may keep standard web server records, such as your IP address and browser type, as covered by Netlify's privacy policy. The app adds nothing to those records.
Deleting your data
Use Clear log in the app to delete the timing log, or clear this site's data in your browser settings to delete everything on your phone, including settings, sound fingerprints and your license key (keep a copy of the key first). To have your order details removed from our records, email support@cyclesensecounter.com; Polar keeps what the law requires for payments and tax.
Children
CycleSense Counter is a tool for measuring machines and is not directed at children.
