Privacy Policy

Kinbinder · Effective August 11, 2026

Kinbinder keeps your family's health records on your own iPhone. We have no account system and no server that stores your health data, which means we have no way to read it.

What Kinbinder stores

You choose what to record. It may include:

All of it is stored on your device. If you have iPhone backup turned on, this data is included in that backup and protected by it.

When Kinbinder connects to the internet

There are only three cases, and every one of them is triggered by you tapping a button:

Outside of these, Kinbinder does not send anything anywhere.

Who processes that data

AI requests pass through a relay we operate on Cloudflare Workers, which forwards them to the AI provider and returns the result. The relay does not store request or response contents.

AI processing is performed by Google (Gemini) and Anthropic (Claude) under their commercial API terms, which do not permit using submitted content to train their models.

If you are in the EU or UK, health information is special category data. Our legal basis for sending it is your explicit consent, given when you tap "Extract" or "Explain." You can use Kinbinder entirely without those features — everything else works offline.

What we never do

Data we do collect

None. Kinbinder has no analytics, no crash reporting SDK, no advertising identifier and no user accounts. The app's Privacy Manifest submitted to Apple declares zero collected data types.

The app stores a few non-health settings locally on your device using Apple's standard preferences system: your language choice, whether you have accepted the terms, and a monthly counter of how many AI operations you have used. It also reads file timestamps to order your documents by date. None of this leaves your device.

Your rights

Because we hold no copy of your data, requests to access or erase it are things you carry out yourself inside the app — there is nothing on our side to retrieve or delete.

Children

Kinbinder is intended for adults. If you create a record for someone under 18, the app asks you to confirm that you are their parent or legal guardian. We do not knowingly collect information from children.

Kinbinder is not medical advice

Kinbinder is a tool for organizing medical records. It is not a medical service and does not provide diagnosis or treatment recommendations. AI-extracted values are always shown to you for review against the original document before they are saved, and AI explanations are written to raise questions for your doctor — not to answer them. For medication, dosage and any care decision, rely on the original documents and your clinician.

Changes to this policy

If this policy changes in a way that affects how your data is handled, we will update the effective date above and describe the change in the app's release notes.
