Privacy Policy (Kidney Notes for Cats)

Last updated: September 25, 2026

Pocket Tools (operated by Steelstyle K.K., "we") sets out below how the smartphone app "Kidney Notes for Cats" (also published in Japan as「にゃん腎ノート」, the "App") handles user information.

1. Information we collect and how it is used

All data you enter in the App — your cat's name, weight, care logs, lab values, photos and notes — is stored only on your device. It is never sent to our servers. We operate no server that receives your data.

2. What this App is (and is not)

The App supports record-keeping for pet care. It does not provide veterinary diagnosis, treatment, or medical advice. Please consult your veterinarian for any decisions about your pet's health.

3. Subscriptions

The optional Premium subscription is processed entirely by Apple (App Store) or Google (Google Play). We do not receive or store your payment details.

4. Sharing with third parties

We do not provide user information to third parties, except where required by law.

5. Deleting your data

Because all data is stored only on your device, uninstalling the App deletes all of it. You can also export a backup file at any time from the More tab; backup files are saved wherever you choose and are under your control.

6. Children's privacy

The App does not knowingly collect personal information from children under 13.

7. Changes to this policy

This policy may be updated from time to time. Material changes will be announced in the App or on the store page.
