Yes — and here is exactly how it works.
Trust in a promo-code tool rests on three pillars: codes that are actually verified, ranking that can't be bought, and an extension that respects your privacy. This page walks through each one — and links to the binding versions in our terms and privacy policy.
A real company, on the record.
Couponly is operated by , a private limited company registered in Estonia. The full registry details are in the who-we-are section of our Terms, and the story of what we're building is on the about page.
You always reach a real person: email [email protected] or use the contact page — there is no chatbot to get past.
Verified means recently observed live.
Across more than 30,000 stores, our systems continuously find promo codes on the web and read store pages with machine learning. An AI layer then tests offers and filters out the ones that no longer work. And at checkout on a supported store, the free extension runs the last mile: it tries our verified codes against your real cart and keeps the one that lowers your total the most.
One honest caveat, straight from our terms: availability, eligibility, and discount amounts are decided by the merchant alone and can change or expire at any moment. A “verified” label reflects what our automated systems recently observed — a freshness signal, not a guarantee that a code will work for your order.
Merchants cannot pay for placement.
Couponly may earn a commission from a merchant or its affiliate network when you shop using our codes or links. That never costs you anything: you never pay more because we earned a commission — if a code or link changes your price at all, it lowers it.
Commissions also never influence whether a code is shown as working or how offers are ordered. Ordering is driven only by freshness (how recently our systems observed an offer), measured success rates (how often a code actually worked for shoppers who tried it), and — for product offers — price.
We respect other people's referrals too: if an affiliate attribution is already attached to your visit — say, a creator's link you followed to the store — we do not overwrite it just because Couponly is installed. The binding version lives in How we make money in our Terms.
What the extension will never do.
Collect payment details
No payment details — ever. No keystrokes, form contents, or clipboard reading, and no raw page content: it reads catalog facts off product pages and discards the rest.
Talk to anyone but us
Everything the extension collects goes to couponly.ai and nowhere else — its background process refuses to send collected data to any other server.
Ignore your switches
Product-data sharing, price-history lookups, and crash reports each have a toggle in the extension's options. Off means off, immediately.
Force an account on you
Testing codes works fully signed out. Price watches are the one signed-in feature — sign in for those and your watches follow you across devices.
The full details — every signal, every switch — are in our Privacy Policy, written to match what the code actually does; the extension itself is on the extension page.
Grounded content, correctable data.
Some content on Couponly — store guides, policy summaries, product descriptions — is generated with AI assistance and passes automated grounding checks: stated numbers must be traceable to the store's own pages. It can still contain errors or go stale, so if you spot something wrong, tell us via the contact page and we will correct it.
Our systems collect data from publicly accessible pages — primarily merchant-published sitemaps — plus publicly distributed codes and signals contributed by our users. Merchants can ask us to correct data, stop collection from their site, or delist their store entirely.
Store reviews can only be posted from a real signed-in account and must pass automated spam checks. Unless a review is explicitly marked as verified, we make no claim that the reviewer purchased from the store.
The questions people actually search.
Is Couponly legit?
Yes. Couponly is operated by a private limited company registered in Estonia, reachable at [email protected], and everything on this page — how codes are verified, how offers are ordered, what the extension collects — summarizes the same commitments made in our Terms of Service and Privacy Policy.
Is the extension safe to install?
It is built to know as little about you as possible: no payment details, no keystrokes, no form contents, no raw page content. Everything it does collect goes to couponly.ai and nowhere else, and product-data sharing, price-history lookups, and crash reports each have a real off switch in its options.
Does Couponly cost anything?
No. The website and the browser extension are both free to use — no subscription, no paywall.
How does Couponly make money?
Through affiliate commissions from merchants when you shop using our codes or links. A commission never raises your price — if a code or link changes your price at all, it lowers it — and commissions never influence ordering: offers are ranked only by freshness, measured success rates, and price. Merchants cannot pay for placement.
Does it track my browsing?
No — it never collects your browsing history. It looks for coupon fields and product details on store pages, sends anonymous signals about whether codes worked, and shares product info from store product pages to power price history — you can switch that off in the extension options.
