Privacy Policy
Last updated: October 13, 2026
Fuji Bit Inc. ("we") respects user privacy in our mobile app TOKIDOKEI (the "App"). This policy explains what information the App collects, how it is used, where it is stored, and which third parties may receive it.
See also our Personal Data Handling & Deletion page for a plain-language summary of the data we handle and how to delete it.
1. Information We Collect
The App collects the following information. None of it is transmitted to our servers (ad-related data is handled by our ad partner Pangle, as described below).
- Phone usage time: Obtained via Screen Time API (FamilyControls / DeviceActivity) on iOS, or UsageStatsManager on Android. We read your total device screen time (you do not need to select specific apps). The per-app and per-category breakdown is computed and displayed on-device only and is never sent to our servers.
- In-app data: Crystal earning history, streak counters, daily quest completion, freeze day usage, settings.
- Ad-related data: To show ads in the free version (a banner at the bottom of the screen and an optional rewarded ad for rerolling a daily quest), the Pangle ad SDK (Bytedance Pte. Ltd.) built into the App collects device information (model, OS version, language, etc.), approximate location inferred from your IP address, ad interactions (impressions, taps), crash and performance data, and advertising identifiers (the IDFA on iOS only if you allow tracking via App Tracking Transparency; the Advertising ID on Android). Personalized ads using the advertising identifier are shown only if you allow tracking via ATT on iOS, or choose "Allow" in the in-app "About ads" dialog on Android; otherwise non-personalized ads are shown. No ads are shown while you are a Pro subscriber.
- Purchase / subscription status: Your Pro (monthly subscription) entitlement. Billing is handled by the App Store / Google Play and is never sent to our servers. The App stores only the entitlement state on-device.
We do not directly collect or hold on our servers any personally identifiable information such as name, address, phone number, or email. Ad-related data is handled by Pangle for ad delivery, as described above. In some jurisdictions, advertising identifiers may be treated as personal information.
2. How We Use the Information
- To provide the App's core features (time visualization, crystal calculation, ranking, notifications)
- To serve and measure in-app advertising and prevent ad fraud (via Pangle)
- For optional iCloud sync (iOS, planned), within the user's own Apple ID across their devices
3. Where Data Is Stored
- By default, all collected information is stored only on the device.
- If iCloud sync is enabled (iOS, planned), the data is shared between your devices through your Apple ID via Apple CloudKit. It is never sent to our servers.
- On iOS, the Screen Time API provides app information as opaque tokens for privacy, and app names and icons are drawn by the OS. On Android, UsageStatsManager provides only the foreground time of each app (package name and timestamps). In both cases we have no access to specific app contents or network traffic, and the per-app breakdown is computed and displayed entirely on-device.
4. Data Retention
- Data stored on the device (usage time, crystal history, settings, etc.) is retained on the device until you delete the App or run "Reset all data" in the in-app Settings. It is never retained on our servers.
- Collection, retention, and deletion of ad-related data (including advertising identifiers) follow Pangle's policy and your permission settings. See the Pangle Privacy Policy for details.
5. Third-Party Sharing
- Pangle (Bytedance Pte. Ltd.): For ad delivery, measurement, and fraud prevention, the ad SDK sends the ad-related data described above (advertising identifiers, device information, approximate location, ad interactions, crash and performance data) to Pangle. Data is encrypted in transit. We do not sell your data. See the Pangle Privacy Policy for details.
- We do not share data with any other third party.
6. Your Rights & Withdrawing Consent
- You can delete all in-app data at any time from the in-app Settings screen.
- iOS: You can deny tracking in the App Tracking Transparency (ATT) dialog shown at launch, or change it any time via "Settings > TOKIDOKEI > Allow Tracking" (or "Settings > Privacy & Security > Tracking") on your device. "Settings > Privacy options (ad consent)" inside the App also opens this screen. If you do not allow tracking, non-personalized ads are shown.
- Android: You can choose "Don't allow" in the "About ads" dialog shown at first launch, or change your choice any time from "Settings > Privacy options (ad consent)" inside the App. This choice is not backed up or transferred to a new device, so you will be asked again there. You can also reset or delete your Advertising ID in your device settings.
- You can revoke Screen Time API / UsageStatsManager permission at any time from OS settings.
- iCloud sync (planned) can be toggled on or off.
7. Use by Children
The App does not impose an age limit, but if used by anyone under 13, it should be with parental consent. We do not knowingly collect personal information from children under 13.
8. Changes to This Policy
This policy may be revised in response to legal changes or App updates. Material changes will be announced in the App or on this site.
