Data Retention & Deletion Policy

Effective Date: 1/10/2026

Knit is designed to give you control over how your health data is stored, shared, and removed.

This policy explains what happens to your data at each stage.

  1. Local Data on Your Device

When you connect a wearable of app, your health data is:

  • stored locally on your device

  • encrypted and protected by your device's security

Logging out of the app does not delete this data, so your history isn't lost if you switch devices or sessions.

  1. Sharing Data with Knit

You can choose whether wearable data, app data, and/or medical record data is shared with Knit's servers.

  • Sharing OFF:
    No new data is uploaded.

  • Sharing ON:
    Data is securely uploaded so it can be used across devices and features.

Only new or changed data is uploaded—unchanged data is not re-sent.

  1. What Happens When You Turn Sharing Off

Turning sharing off:

  • Immediately stops future uploads

  • Does not delete data that was previously shared

Previously shared data remains securely stored so your experience and history stay intact.

  1. Deleting Your Data

If you request full account deletion:

  • All of your data is permanently deleted from Knit's servers

  • Your accout and associated records are removed

  • Active sessions are invalidated

Some data may not be deletable if it was previously shared outside of Knit (for example, with research partners, if you opted in). This will always be disclosed clearly.

  1. Transparency & Accountability

Key actions—such as enabling sharing, disabling sharing, and deleting your account—are logged securely so Knit can verify that your choices are respected.

  1. Privacy and Security

Your use of the Services is subject to our Privacy Policy and Security Policy, which describe how we collect, use, store, and protect your information.

By using the Services, you agree to those policies.

Your Control Comes First

You decide:

  • What's shared

  • When sharing stops

  • When data is deleted

Knit's systems are built to enforce these choices.
