At Paplu Physics (operated by Wide Future Classes), your privacy is important to us. This policy explains what information we collect, how we use it, and the steps we take to keep it safe.
Every PDF you download contains an invisible watermark uniquely tied to your account. This watermark is used solely to identify the source in the event that a PDF is illegally shared or distributed. It does not affect the content, quality, or readability of the paper.
We do not sell, rent, or trade your personal information to any third party. We share data only with:
Your data is stored in Supabase's encrypted cloud infrastructure. Access is restricted to essential personnel only. Download links for PDFs are time-limited and signed — they cannot be shared with others. Passwords (if applicable) are hashed using industry-standard algorithms.
We retain your account data as long as your account is active. If you wish to delete your account, contact us at the address below and we will erase your data within 30 days, except where retention is required by law (e.g., transaction records).
We use minimal, essential cookies to keep you logged in. We do not use advertising or tracking cookies. Your language preference is stored in your browser's local storage.
Our services are intended for students aged 14 and above. We do not knowingly collect data from children under 13. If you believe we have inadvertently collected such data, please contact us immediately.

We may update this policy occasionally. Significant changes will be notified via your registered contact. Continued use of the platform after changes constitutes acceptance of the updated policy.
