Last updated: 2026. This policy explains what information SABIBOOK collects and how it is used.
SABIBOOK does not require you to create an account or give your name, email, or phone number. When you use the site, your browser is given a random anonymous ID, stored only on your own device, used to check your daily free question count and your Pro status if you subscribe.
When you snap or upload a photo of a question, it is sent securely to our AI provider (Google's Gemini API) to be read and solved. We do not store your photos on our servers. Your recent answers are saved only in your own browser's local storage, never uploaded to us, and are cleared automatically on the schedule shown in the app.
If you subscribe to SABIBOOK Pro, your payment is handled entirely by Paystack, a licensed Nigerian payment processor. We never see or store your card details. We only receive confirmation that a payment succeeded, tied to your anonymous ID, so we can activate Pro.
SABIBOOK shows ads through Google AdSense to keep the free tier free. Google and its partners use cookies to serve ads based on your visits to this and other sites. You can learn more about how Google uses this data, and manage your ad personalization settings, at policies.google.com/technologies/ads. Going Pro removes these ads entirely.
Google (AdSense, and Gemini for reading and solving questions), Paystack (payments), Supabase (storing subscription status and daily usage counts tied to your anonymous ID, never your identity), and Vercel (hosting).
Since SABIBOOK doesn't collect personal identifying information, there is no account to delete. Clearing your browser's local storage removes your saved answers and anonymous ID immediately.
