Introduction

Kumbukum ("we", "us", "our") operates the kumbukum.com website and the Kumbukum service. This Privacy Policy explains what data we collect, how we use it, and your rights.

What we collect

  • Account information — email address and password hash when you sign up.
  • Content you store — notes, memories, tags, and any other data you save through our app or API.
  • Usage data — basic server logs (IP address, request timestamps, user agent) for security and debugging. We do not use analytics trackers.
  • Payment information — processed by our payment provider. We never store credit card numbers.

How we use your data

  • To provide and maintain the Kumbukum service.
  • To authenticate you and secure your account.
  • To respond to support requests.

What we do NOT do with your data

This is the most important section:

  • We do not use your data to train AI models. Your notes, memories, and any content you store are never fed into machine learning training pipelines — ours or anyone else's.
  • We do not scan, read, or analyze your content. Your data is yours. We do not mine it for insights, advertising, or any other purpose.
  • We do not sell, rent, or share your data with third parties for marketing or any commercial purpose.
  • We do not serve ads.

Data storage and security

Your data is stored on secure servers. All connections are encrypted via TLS. Passwords are hashed with bcrypt. We apply reasonable security measures to protect your data, but no system is 100% secure.

Data retention and deletion

Your data is retained as long as your account is active. You can delete individual notes, memories, or your entire account at any time. When you delete your account, all associated data is permanently removed from our systems within 30 days.

Your rights

You have the right to:

  • Access all data we hold about you.
  • Export your data at any time via the API.
  • Delete your data and account.
  • Request corrections to your personal information.

Cookies

We use a single session cookie to keep you logged in. We do not use tracking cookies, third-party cookies, or fingerprinting.

Changes to this policy

We may update this policy from time to time. Material changes will be communicated via email or a notice on the site. The "Last updated" date at the top reflects the most recent revision.
