Privacy policy

Last updated: 22 Oct 2026

We respect your privacy and collect as little as possible — only what's needed to protect your summary.

What we collect when a summary is opened

• A random ID stored in a cookie in your browser, so your device is recognised next time.
• A device fingerprint: general technical properties such as device and browser type, screen size, time zone, language and hashed graphics signatures that don't reveal who you are.
• IP address and time of each opening or attempt.

Why

To link the summary to its owner's devices, stop it from opening on other devices, and spot attempts to share it.

What we don't do

• We don't use this data for advertising, sell it, or share it with third parties.
• We don't track you outside Lubb links.

How long we keep it

Opening logs and attempts are deleted automatically after 180 days. Linked-device data stays while the summary exists and is deleted with it.

Order details

Chat and payment happen on Telegram. We keep your name, contact and amount paid only to manage your order.

Your progress inside a summary

What you save inside a summary (answers, reading position) is stored in your own browser.

Your rights

You can ask to see or delete your data at any time on Telegram.
