Companies have got very good at making complaints disappear. A form that goes nowhere. A chatbot that closes the ticket. A reply that says "we've noted your concerns" and nothing changes.
Stamped exists because the only thing that reliably changes a company's behaviour is the thing they can't quietly file away — enough people, saying the same thing, at the same time, on the record.
We will never sell your data, to anyone, for any reason.
We will never reveal who submitted a complaint — not to the company, not to journalists, not to anyone.
We will never publish or notify anyone before a threshold is genuinely, verifiably reached.
We will never require an account, a password, or your real name to use Stamped.
If we ever break one of these, that's the day Stamped should be shut down — and we mean that.
"I built this after watching complaints disappear into the same void over and over — mine, and other people's. Not because anyone did anything illegal. Just because nobody had a reason to listen to one person.
I don't know yet if 50 is the right number. I don't know if this works at all. But it's free, it's anonymous if you want it to be, and it's better than the alternative — which is nothing."

Got something to log?
Log your complaintStamped (stamped.org.uk) is the data controller. Questions or requests: hello@stamped.org.uk.
Just three things: which company, what happened, and what outcome you want. An email address is optional, and only used to notify you if something happens with a pattern you're part of.
Complaint data is processed under legitimate interest — identifying patterns of consumer harm and holding organisations accountable. Where you provide an email address, that's processed on the basis of consent, which you can withdraw any time.
Complaint data is retained for up to 3 years, for as long as it remains relevant to an active or potential pattern. Email addresses are kept only until a relevant threshold is reached, or 12 months, whichever is sooner.
Using infrastructure providers based in the UK, EU, or US, operating under appropriate data protection safeguards (including Standard Contractual Clauses where applicable).
We do not sell, rent, or trade your data to anyone, for any purpose.
Under UK GDPR you have the right to access, rectify, erase, restrict or object to processing, withdraw consent, and request data portability. Email hello@stamped.org.uk — we'll respond within one month. If you're unhappy with how we've handled things, you can also complain to the ICO.
Stamped isn't directed at anyone under 18. If you believe a child has submitted data, contact us and we'll remove it.
You don't need to provide an email or any identifying information. If you don't, we have no way to identify or contact you — your submission is anonymous from the point of receipt.
We may update this page as Stamped develops. Material changes will be reflected by updating the date below.
