Effective July 8, 2026 · Version 1.0
When you submit content — a text, email, link, ad, or description — it is processed in memory to produce your verdict and is not stored by us afterward. We do not keep a history of your checks, and we cannot show them to anyone, because they do not exist after we answer you.
To produce a verdict, your submitted content is sent securely to our AI provider, Anthropic, which analyzes it and returns the result. Under Anthropic’s API terms, content sent this way is not used to train their AI models. If your content contains a web link, we also look up public registration records for that website’s domain name (for example, how old the website is). Only the domain name is sent for that lookup — never your message or personal details — and we never visit the suspicious link itself.
Our hosting provider (Vercel) keeps standard, short-lived server logs — such as IP address, browser type, and request time — used for security and keeping the service running. We currently run no advertising trackers and no third-party analytics on the service.
When accounts and paid plans launch, we will collect what a subscription needs and no more: your email address, your plan, and a count of checks used (a number — not the content of your checks). Payments will be processed by Stripe; your card number goes to Stripe, not to us. Family plans are designed so that each person’s checks stay private to them — being on a shared plan never means being watched.
We do not sell or rent your personal information. We do not share your content except with the service providers named in this policy, and only to answer you. We do not use your content to train AI models. We do not run ads. If any of this ever changes, we will update this policy and tell you first — but our plan is that it never changes, because privacy is the product.
We use a small number of providers to run CheckTwice: Anthropic (AI analysis), Vercel (hosting), and Cloudflare (domain and network services). When payments launch: Stripe (billing). Each receives only what it needs to do its job.
Depending on where you live (including California and other U.S. states with privacy laws), you may have rights to access, correct, or delete personal information, and to know how it is used. Because we keep so little, most requests are simple: email hello@checktwice.app and we will handle it. We honor Global Privacy Control signals where required. We will never treat you differently for exercising a privacy right.
CheckTwice is for adults and is not directed to children under 18. We do not knowingly collect personal information from children. If you believe a child has provided us personal information, email us and we will delete it.
All connections to CheckTwice are encrypted (our .app domain requires it). We minimize what we hold — the strongest protection for your data is that we do not keep it.
If we change this policy, we will post the new version here with a new effective date, and notify account holders of material changes before they take effect.
