Privacy and data retention

SpamLens processes group images only to check them against the rules that group's admins set. Images and temporary Telegram file links are never saved.

Each image is sent once to Cloudflare Workers AI Vision to copy out its text, and the image is discarded as soon as that request finishes.

What we keep: group settings, rules, scan balances, Telegram Stars charge IDs, the text read from images (deleted after 24 hours, never shared between groups), and short redacted activity records (deleted after 14 days).

Any current admin can send /deletedata to the bot in a private chat to delete the group's rules, trusted members, text cache, activity log and balance. Payment records are kept as required for accounting and refund checks.
