Privacy policy
Last updated November 6, 2026
This page explains what information StickieTime (called FusenTimer in Japanese; "the app") and this website handle, and how. The app is made by Kenichi Kasuya, an independent developer.
The app doesn't send your information to our servers, and there's no account to create. Your notes and timer settings are stored only on your device.
What is stored on your device
- Your notes (text, checklists, start times and lengths) and their color, paper, style and font
- Folders, sort order, and notes in the trash
- Timer settings, presets and app settings
- Whether you've made the purchase
All of this stays in the app's own storage on your device and is never sent anywhere. Deleting the app deletes it too. Notes you move to the trash are deleted after 30 days.
Purchases
The purchase that removes the limits goes through the App Store or Google Play. Apple or Google handle your payment details; we never receive them. The app asks the store only whether you've made the purchase.
Notifications, vibration and keeping the screen on
Alerts for the end of a timer and for a note's start time are scheduled on your device (local notifications). No outside server is involved. You can change notification permission in your device settings at any time. Vibration and keeping the screen on while timing use your device's own features and send nothing.
Ads and analytics
The app has no ads. It doesn't collect usage analytics or track you across other apps or websites.
This website
This site uses no cookies and no analytics. It is served through Cloudflare, which may handle access records (such as IP addresses) to deliver the site and keep it secure. If we ever add analytics, we'll update this page first.
Children
The app doesn't collect personal information, so people of any age can use it.
Changes to this policy
If this policy changes, we'll update this page and the "Last updated" date above.
