Privacy policy

The short version

Sach doesn't have accounts, doesn't ask for your name, and doesn't sell data. Here is exactly what happens to what you paste or pay.

When you check a forward

Your text is split into separate claims. Each claim is sent to search sources and to AI language-model providers (currently Google Gemini, with fallbacks to other providers) so they can compare it with official pages. Don't paste anything private, like personal details or one-time passwords.
If you upload a screenshot, the image is sent to Google's Gemini service to read its text. Sach does not store the image or the text it reads.
A share link shows the checked message and Sach's result to anyone who has the link; it expires when the stored result expires (7 days for TRUE/FALSE/MISLEADING, 6 hours for UNVERIFIED); links are not indexed by search engines.
If you share an image into Sach, it is sent to Google's Gemini to read the text, and it is not stored.
For each checked claim Sach keeps a public record in the evidence ledger: the claim text, its verdict, the sources cited, the language and the date. The full original message, your name, your phone number and your IP address are not stored in that record.
On your device only: "My checks" keeps your last 20 checks (the claim, its verdict and the date) in your browser's local storage. It never leaves your device, and you can clear it from the page. Sach's service worker saves only the public home page, the icons and the app manifest for offline use, never your text or results.
To limit abuse, the server briefly remembers your IP address in memory to count requests per minute. The hosting provider (Vercel) may also keep standard server logs.

When you tip

Card / UPI checkout: payment is handled by Razorpay. Razorpay collects the details needed to process the payment and may show the operator your name, contact and payment method in its dashboard. Sach itself never sees or stores your card, UPI or bank details. Razorpay's own privacy policy applies to that data.
UPI QR code: the payment goes directly between your UPI app and the operator's bank account. Sach doesn't see it.
Sach doesn't link tips to the claims you checked.

Visit statistics

Sach uses Vercel Web Analytics to count page views. It does not use cookies and does not identify you; it does not see what you paste into the checker.

Cookies

Sach doesn't set tracking cookies. Your browser may store your light/dark preference locally. Razorpay's checkout window, when opened, may set its own cookies.

Your choices

You can use Sach without tipping. To ask about data tied to a payment, contact Razorpay or open an issue on GitHub. The public ledger holds claim text only. If a claim in it contains personal information, tell us and we'll remove it.
