Services involved
- Cloudflare delivers connections to this site and checks that a message was sent by a person (Turnstile).
- Telegram notifies the operator of new messages. The notification includes the message.
Visits
- Visits are counted with Cloudflare Web Analytics, which uses no cookies and does not identify individual visitors.
- If you choose light or dark mode, that choice is stored only in your browser and never sent to the server.
