Personal Data Handling & Deletion
Last updated: October 13, 2026
Fuji Bit Inc. ("we") handles personal data in the TOKIDOKEI mobile app (the "App"), including data that cannot identify you on its own such as advertising identifiers, in accordance with applicable laws, as described below. This page is a plain-language summary of the data the App handles - what it is, why it is used, who it is shared with, how long it is kept, and how to delete it. For the full legal text, see our Privacy Policy.
Data we handle
| Data type | Source | Purpose | Leaves the device? |
|---|---|---|---|
| Smartphone usage time (total device screen time; per-app / per-category breakdown computed on-device) | iOS: Screen Time API (FamilyControls / DeviceActivity) Android: UsageStatsManager |
Usage visualization and crystal calculation (core feature) | No (processed on-device only) |
| In-app data (crystals, streaks, quest progress, Freeze Days, settings) | App usage | Saving and displaying your progress | No (on-device only) |
| Ad-related data (advertising identifier IDFA / Advertising ID, device information, approximate location inferred from IP address, ad interactions, crash and performance data) | Pangle SDK (Bytedance Pte. Ltd.) | Ad delivery, measurement, and fraud prevention (personalized only with permission) | Yes (Pangle). The advertising identifier is used for personalization only if you allow tracking via ATT on iOS, or choose "Allow" in "About ads" on Android. No ads are shown to Pro subscribers |
| Purchase / subscription status | App Store / Google Play billing | Providing Pro (monthly subscription) | Billing handled by Apple / Google; the app stores only the entitlement state on-device |
We do not collect or hold any personally identifying information (name, address, phone number, email, etc.) on our own servers. There is no account creation or login.
Why we use it
- To provide the core features: visualizing screen time and calculating crystals, streaks and quests (processed on your device only)
- To show in-app ads, measure ad performance and prevent fraud (by our ad partner Pangle; ads are personalized only if you allow it)
- To provide Pro (monthly subscription) and check your subscription status
- To reply to your inquiries (only the content and email address you send us)
We do not use the data for any other purpose.
Sharing with third parties
- We do not sell personal data.
- In the free version, the Pangle ad SDK (Bytedance Pte. Ltd., Singapore) built into the App collects the ad-related data listed above to serve ads, measure their performance and prevent fraud. The data may be processed outside your country, for example in Singapore. The ad SDK is not started while you are subscribed to Pro.
- Payments are processed by Apple (App Store) or Google (Google Play). We do not receive your card or other payment details.
- We do not share data with any other third party except where required by law.
How long data is kept
- Data on your device is kept until you use "Reset all data" in the App or delete the App. We do not keep it on our servers.
- Ad-related data is kept according to Pangle's policy.
- Inquiry emails are deleted once they are no longer needed to handle your request.
Security
App data is stored in storage protected by the operating system, and network traffic is encrypted with HTTPS. Because of how the operating system works, screen time data never leaves the App's protected environment.
Where data is stored
- As a rule, all data is stored only on your device and is never sent to our servers.
- Ad-related data is handled by our ad partner Pangle in accordance with its policy (Pangle Privacy Policy).
- If you enable iCloud sync (iOS only, planned for a future release), data is shared across your devices solely within your own Apple ID via Apple's CloudKit.
How to delete your data
- Delete in-app data: Use "Settings > Reset all data" in the app to erase all on-device data, including crystals, streaks, quests, and settings.
- Uninstall the app: Removing the app from your device erases all data stored on the device.
- Change personalized-ads permission (Android): Change or withdraw it anytime via "Settings > Privacy options (ad consent)" in the app.
- Change tracking permission (iOS): Adjust it under iOS "Settings > TOKIDOKEI > Allow Tracking" (also reachable from "Settings > Privacy options (ad consent)" in the app).
- Revoke usage-access permission: Revoke Screen Time API / usage-access permission anytime in your OS settings. If you do not grant it, or revoke it later, automatic usage tracking stops. So you do not miss this, the app shows an in-app banner and sends one reminder notification per day; re-granting the permission stops the notification automatically.
- Reset the advertising identifier: Reset or delete your advertising ID in your device's OS ad settings.

Access, correction and deletion requests
We do not hold information that identifies you, such as your name or email address, so you can review and delete the data on your device yourself as described above. For any other request to access, correct, stop using or delete personal data, please contact us at the address below. We will verify your identity and respond without undue delay as required by law. You can also contact Pangle directly about ad-related data.
Children
If you are a minor, please use the App with the consent of a parent or guardian.
