Privacy Policy

Last updated: March 2026

Information We Collect

We collect the information you provide when creating an account (name and email address) and information needed to connect your devices (such as reMarkable OAuth tokens or your Kindle email address). We also collect URLs you submit for conversion.

How We Use Your Information

We use your information solely to provide the Collater service — converting URLs to EPUBs and delivering them to your connected e-reader. We do not sell, rent, or share your personal information with third parties for marketing purposes.

Data Storage and Security

Your data is stored securely. Device credentials (such as reMarkable tokens and Kindle email addresses) are encrypted at rest. We retain your data for as long as your account is active.

Third-Party Services

Collater interacts with third-party services on your behalf, including the reMarkable cloud API and Amazon's Send to Kindle service. Your use of those services is subject to their respective privacy policies.

Cookies and Sessions

We use encrypted cookies solely to maintain your authenticated session. We do not use tracking cookies or third-party analytics cookies.

Your Rights

You may request deletion of your account and associated data at any time. Upon deletion, your personal information will be removed from our systems.
