Crisp Widget for Fasting
Privacy Policy
This English version is provided for convenience. The Japanese version is the original.
This policy explains how d mark ("we", "us") handles information in the Android app "Crisp Widget for Fasting" (the "App").
1. Summary
Your fasting records and weight entries are stored only on your device and are not sent to us or to any third party. The App has no internet access, no account, no ads, and no analytics or crash-reporting tools.
2. Information stored on your device
The App stores the following in its private storage on your device (other apps cannot read it):
- your fasting/eating cycle (start times and plan) and fasting records (start, end, goal and whether it was completed);
- weight entries (date/time and value; a Paid Feature);
- settings such as plans, weekday schedule, weight unit and notifications on/off, and widget display settings;
- whether you have bought the Paid Features, accepted the disclaimer, and whether a notification has been shown.
Fasting records older than 800 days are deleted automatically. Weight entries are kept until you delete them. All data is deleted when you uninstall the App or clear its storage.
3. Health-related information
Fasting records and weight are information about your health. The App does not send them off your device, and we never receive them.
4. CSV export
Only when you use CSV export (a Paid Feature), the App writes your fasting records or weight entries to a CSV file at the location you choose in Android's file picker. If you save to cloud storage (such as Google Drive), that service handles the file under its own policy. You are responsible for managing exported files.
5. Device backup
The App supports Android backup. If you have turned on Google backup in your device settings, the data in Section 2 (including fasting records and weight) may be backed up to your Google account by Android and restored, for example when you move to a new phone. This backup is managed by Google, and we cannot see its contents. You can turn backup off in your device settings.
6. Permissions
| Permission | Purpose |
|---|---|
| Run at startup (RECEIVE_BOOT_COMPLETED) | To reschedule phase changes, notifications and display updates after the device restarts |
| Notifications (POST_NOTIFICATIONS) | To tell you when fasting or eating starts. Requested only when you turn notifications on |
| Alarms & reminders (SCHEDULE_EXACT_ALARM) | To switch phases, notify and update the display on time. Used only if you allow it; the App works without it |
7. Purchases
Purchases are processed by Google Play. The App only checks with Google Play whether you have made a purchase. From Google we receive information needed to manage sales and handle refunds, such as order number, purchase date and country/region; we do not receive your credit card number or other payment details. See Google's Privacy Policy (https://policies.google.com/privacy).
8. When you contact us
If you email us, we receive your email address and message (including any device model or OS version you mention). We use them only to reply and investigate issues, do not share them with third parties except as required by law, and delete them once no longer needed. You do not need to tell us about your health.
9. Children
The App is not directed to children under 13. We do not collect personal information from children through the App. Users under 18 should consult a doctor before use (see the disclaimer).
10. Regional information
- Japan (Act on the Protection of Personal Information): the only personal information we obtain is described in Sections 7 and 8. Requests for disclosure, correction, suspension of use or deletion can be sent to the contact below.
- EEA/UK (GDPR): we do not process personal data (including health data) in connection with your use of the App. Information you send us by email is processed in Japan to answer your request (legitimate interests); Japan has an EU adequacy decision. You have the rights of access, rectification, erasure, restriction and objection, and may complain to your local supervisory authority.
- California (CCPA/CPRA), Washington (My Health My Data Act) and other US states: we do not collect or sell personal information (including consumer health data) or share it for targeted advertising.
11. Changes
We may update this policy when the App's features or the law change. The updated policy will be posted on the support site, and for important changes (such as the App starting to send information off the device) we will give notice before the App update.
