Consent and withdrawal
You ticked a box on someone’s tap page. This page says exactly what that box did, what was written down, and how to undo it.
One box is one channel
The boxes are separate because the permissions are separate. Ticking “email me the rates” does not permit a WhatsApp message, and neither of them puts you on a newsletter. Ticking nothing sends nothing — there is no implied channel and no default.
What was written down
Consent is stored as an append-only row. Nothing overwrites it, including a withdrawal: the withdrawal is another row. That is the only way to show, a year later, both that you agreed and that you stopped.
- Channel
- Email, WhatsApp, Telegram or newsletter — the one you ticked.
- Consent text
- The exact wording shown to you, not a summary of it.
- Version
- The version of that wording, so a later change cannot be applied backwards.
- Hash
- A SHA-256 of the text, so the stored wording can be proved unaltered.
- Timestamp
- When you ticked it, to the second, in UTC.
- Card and profile
- Whose card you tapped, so you know who is writing to you.
How to stop it
- Reply STOP to any message on a messaging channel. It takes effect immediately, on that channel.
- Use the unsubscribe link in any email. It stops email; it does not silently stop the others, because they were separate permissions.
- Reply asking for a person. The thread is handed to the cardholder and the agent stops writing in it.
- Ask the cardholder to delete you entirely. The lead goes; the consent and withdrawal rows remain as evidence.
A withdrawal is checked at the moment a message is about to be sent, not when it was written. A draft prepared five minutes before you replied STOP does not go out.
What happens on the other side
Before anything reaches you, a deterministic gate runs: suppression, consent, the channel window, jurisdiction rules, the AI disclosure, frequency, quiet hours in your own timezone, grounding, and whether the action is one a machine is allowed to take at all. The first failure wins and the full result is stored on the message.
Email to a lead in Germany or Austria is stricter still: under UWG §7 and TKG §174 implied interest is not a lawful basis, so without an explicit double opt-in the gate blocks rather than holds.
Who is writing
The first message in any thread says that it comes from an assistant, in your language. What that means, and how to reach the human.
