Plain English first.

Nothing personal. Safe for humanshas no accounts, no login, no email signup. We don’t collect your name, your location, or contact information. We don’t use third-party analytics or advertising trackers. No cookies are set by us, and no fingerprinting libraries run in your browser.

Four kinds of requests can leave your browser:

• When you type into the search box, your query is sent to our backend so we can look up matching products. The same is true if you paste a barcode or a retailer link.
• When you take or upload a photo using the camera button, the image is sent to our backend for AI vision analysis (Gemini, hosted by Google Cloud's Vertex AI). The image is processed in transit and is not retained by us after the response is returned.
• When you visit the Recalls page, we fetch the latest food-safety alerts from our backend. No information about you is included in that request.
• When you paste a Walmart, Amazon, Target, or Kroger link, a small Cloud Function on our backend fetches that public page to extract a product barcode. The URL you pasted is the only thing transmitted.

These requests carry no identifier that ties them to you. Standard server logs include your IP address briefly for rate-limiting and abuse prevention; they are not retained beyond 30 days and are not joined to any user identity.

A small counter that tracks how many photo scans you’ve used today is stored in your browser’s localStorage to enforce the daily free limit. The most recent photo-scan result is held in sessionStorage so the result page can render after capture. Both clear when you close the tab (sessionStorage) or when you manually clear site data (localStorage). Neither is sent to us.

If you write to us at support@safeforhumans.app we keep your message and reply only as long as needed to help you. Incoming email is forwarded through Cloudflare Email Routing to a personal mailbox; Cloudflare’s privacy policy applies to that transit.

The website itself does not process payments. Subscriptions to the iOS app are processed entirely by Apple through the App Store; we never see your name, address, or payment information. We receive a signed transaction from Apple confirming you’re entitled to use the subscriber features of the app, and nothing else.

• Google Cloud Platform — hosts our backend (Cloud Run, Firestore, BigQuery) and powers the AI vision analysis (Vertex AI Gemini).
• Cloudflare — provides DNS and (when enabled) email forwarding for our domain.
• Tolt — creator dashboard and payout orchestration for our Creator Program (only handles creator data, not subscriber data).
• Stripe (via Tolt) — pays bounties to enrolled creators (only handles creator data).
• Open Food Facts — community-curated product database (open data, ODbL license).
• USDA FoodData Central — US government product database (public domain).
• NIH Dietary Supplement Label Database — US government (public domain).
• Apple StoreKit — subscription processing for the iOS app.

These services may receive the data described above in the course of answering your scan or search request.

Some links to our app are part of our Creator Program. When you visit a URL like safeforhumans.app/c/jane we record the click on our backend with a one-way hash of your IP address and user-agent so we can show creators how many people clicked their link without storing raw identifiers. If you tap the App Store button, the page copies the creator’s URL onto your device clipboard so the iOS app can read it on first launch (only the URL pattern is read, never the rest of your clipboard). We use this solely to credit the correct creator if you go on to subscribe.

Creators who apply to the Creator Program provide their name, email address, social-media handles, and approximate audience size. If approved, they additionally provide tax and bank information to our payout partners (Tolt and Stripe Connect) to receive bounty payments. See Tolt’s privacy policy and Stripe’s for what those services do with that data.

Safe for humansisn’t directed at children under 13 and we don’t knowingly collect data from anyone.

You can write to support@safeforhumans.app and ask what we have on file. Because we don’t identify users on this website, in most cases the answer will be “nothing.” For the iOS app, you can request deletion of any device-scoped data (scan history is local to your phone — clearing the app removes it).

If we materially change how data is handled, we’ll update this page and bump the date below. For meaningful changes affecting existing users, we’ll surface a notice in the iOS app.
