Privacy Policy
Last updated: July 2026
1. What we collect
We do not collect any personal information through the App. Your records (symptoms, medication, notes), data read from Health, weather data, and app settings are stored only on your device. We operate no server.
2. Health (HealthKit) data
- What is read: sleep duration, heart rate variability, resting heart rate
- Why: to treat them as that day’s conditions and analyze them against your records, entirely on your device
- Nothing is written to Health (read only)
- Health data is never used for advertising and is never shared with third parties
- You can revoke access at any time in the Settings app
3. Location
Location is used only to fetch weather, while you are using the App, at reduced accuracy. It is never stored outside your device. If you decline, you can select a region manually instead.
4. Network connections
The only service the App contacts is Apple’s weather service (WeatherKit). To fetch weather, your location or selected region is sent to Apple. Please refer to Apple’s privacy policy for how Apple handles that data.
The App contains no advertising or analytics SDKs.
5. Deleting your data
Deleting the App deletes every record stored on your device. Export anything you want to keep as PDF or CSV first.
6. Children’s privacy
The App is not directed at children and does not collect personal information.
7. Changes
If we change this policy, we will post the change on this page.

Controller, contact and your rights
This app is provided by freetokyo, an independent developer, who acts as the data controller. For any question about this policy or about personal data, contact freetokyo2020@yahoo.co.jp. We normally reply within five business days.
If you are in the EU, the EEA or the UK, the GDPR gives you the right to access, rectify, erase, restrict and port your personal data, to withdraw consent and to object to processing. You may also lodge a complaint with your national supervisory authority.
If you are a California resident, the CCPA/CPRA gives you the right to know, delete and correct the personal information collected about you, and to opt out of its sale or sharing. We do not sell or share personal information.
Where this app stores data only on your device, we have no access to it, so most of these rights are exercised directly on the device: delete or export inside the app, or delete the app. We will still answer any request you send us.
Retention: on-device data is kept until you delete it or remove the app. Support emails are deleted 24 months after the request is closed.
