Who processes your data

We use these services to run FactSift. Each receives only what it needs for its part.

Google Firebase

Stores your account, checks, screenshots and allowance, runs our servers, and sends notifications. Data is stored in Google Cloud's Mumbai, India region (asia-south1). Firebase privacy

Anthropic (Claude)

Reads the post's text, link preview and screenshot to find its factual claims, then weighs the evidence for each. Anthropic receives the post content but not your account details. Under its commercial terms, Anthropic does not use this data to train its models. Anthropic privacy

Serper

Runs the web searches used as evidence. It receives search queries written from the post's claims, never your account details. Serper privacy

Google Fact Check Tools

We look up the post's claims in published fact-checks. It receives the claim text only.

Websites in posts and search results

To read a linked post or a source, our servers fetch the page. The website sees a request from our servers, not from your phone. For X and TikTok links we use their public embed services.

Google AdMob

Shows banner and rewarded ads, unless you have removed ads. AdMob may collect your device's advertising ID, IP address and device information to show and measure ads. In the European Economic Area, the UK and Switzerland, FactSift asks for your consent first through Google's consent form. You can reset your advertising ID or opt out of personalised ads in your Android settings. How Google uses data from ads

When you watch a rewarded ad, AdMob tells our servers that the ad was completed, together with your FactSift account ID and device key, so we can add your extra check. Google signs this message so it can't be forged.

Google Play and RevenueCat

Google Play handles payment when you buy checks or remove ads. RevenueCat, our purchase-management provider, receives the purchase from Google Play together with your FactSift account ID, confirms it, and tells our servers what to add to your account. We and RevenueCat receive the order details, never your card or payment details. RevenueCat privacy

We don't sell your personal data or share it for anyone else's marketing.

How long we keep it

Your choices

Depending on where you live, including under India's Digital Personal Data Protection Act and the EU and UK GDPR, you may have further rights, such as to object to processing or to complain to a data protection authority. Email us to use any of them.

Security

Data travels encrypted between the app and our servers. Only you can read your own checks and account, and everything you change goes through our servers, which check that the request is yours.

Children

FactSift is not directed at children under 13, and we don't knowingly collect data from them. If you believe a child has used FactSift, email us and we'll delete their data.

AI results

Verdicts are produced by AI from public sources and can be wrong. Read the sources before you rely on a result, and report a verdict you think is wrong from the result screen.

Changes

If we change this policy, we'll update the date above. If a change affects how your data is used, we'll tell you in the app first.
