Keyslate

Privacy

Effective 14 August 2026.

Keyslate turns the listings a real estate agent posts to their public Telegram channel into a map that renters browse. This page describes what we store to make that work, and nothing here is legalese for things we secretly do anyway. If it is not listed, we do not do it.

What we store about renters

  • Your Telegram user id and first name, captured when you tap “Save my map” and open our bot. We use it to send you your map link and messages about new or removed listings.
  • The filters, hearts, and notes on your saved map, so they are still there when you come back.
  • Contact details such as an email or phone number, only if you type them into a form yourself, and only used for the purpose that form states.

What we store about agents

The listings you already published to your Telegram channel, plus your name, photo, and channel details as you configure them. Keyslate republishes what you made public, on your map.

What we never do

  • No selling or sharing of personal data with advertisers.
  • No marketing email or spam messages.
  • No tracking beyond one cookie that remembers you saved a map.

Who processes the data

Keyslate runs on Vercel (hosting), Supabase (database), Cloudflare (media storage), Mapbox (maps), Anthropic (AI listing parsing), Sentry (error monitoring), and Telegram (messages). Each processes data only to provide its part of the service.

How we use AI

To turn a free-text Telegram post into a structured listing (price, location, number of rooms), we send the text of that post to Anthropic’s Claude model. We send only listing text an agent already published publicly, never a renter’s saved-map filters, hearts, notes, or contact details. Under Anthropic’s API terms that text is not used to train their models.

Removal

To have your map and data deleted, ask the agent who shared your link, or email hello@keyslate.io. We delete on request, without ceremony.
