Privacy policy
Last updated: 11 August 2026
What is not collected
This app collects nothing about you. No account is required, and there are no third-party advertising or analytics SDKs.
Where records are kept
Everything — client details, treatments, photos and signatures — is stored on your device only. The app does not send any of it anywhere.
Two features deliberately place a copy outside the app. You choose where it goes:
- PDF export for a single client (for handover or for the client)
- Backup export (an unencrypted JSON file containing names and treatment records; photos and signature images are not included)
Device features
- Notifications: used for patch test expiry and record review reminders. Off by default.
- Face ID / Touch ID: used for the optional app lock. Off by default, and the authentication happens on the device — the app never receives biometric data.
- Photos: the iOS photo picker is used, so the app does not ask for access to your whole photo library. Only the photos you pick are handed to the app.
Purchases
Purchases are handled by Apple's App Store. The developer never receives your payment details.
Deletion
For each client you can remove the identifying details only, or delete everything. Settings also has a delete-all option. Removing the app deletes the records with it.
Contact
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.
