Terms & Privacy Policy
1. The service
Paperly is a web tool that turns photos of documents into scanned PDFs. Image processing (edge detection, perspective correction, whitening and PDF creation) runs locally in your browser; your photos and exported PDFs are never uploaded to our servers. Paperly does not provide OCR and does not certify the authenticity or legality of any document.
2. Accounts
- You can export 1 free PDF a day without an account; more exports, purchases and credits require one. At sign-up you receive a 12-character recovery code, which is the only way to reset a forgotten password. Keep it safe.
- Do not create accounts in bulk, or share, buy or sell accounts. Too many sign-ups from one device or network in a short time are limited.
- Passwords are stored as salted hashes (PBKDF2); we cannot see your password.
3. Free exports and credits
- Guests get 1 free export a day and signed-up users get 3 (reset at 00:00 Beijing time, UTC+8); free exports are up to 3 pages each, and new accounts receive 3 credits. With credits, one credit exports one PDF of up to 30 pages; exporting the same set of pages again within 24 hours is free.
- To prevent abuse, free exports are also capped per device and per network, so several accounts on one device do not multiply the free allowance.
- When the free exports are used up, or a document has more than 3 pages, each export uses 1 credit. Credits are bought or earned through invites, never expire, and cannot be transferred or cashed out.
- Invite rewards: a friend who signs up with your link gets 5 credits; you get 10 credits after their first export, 10 and 30 bonus credits when you reach 3 and 10 rewarded invites, and 20% of the credits in a friend's first purchase. Repeat sign-ups from the same device or network, and invites beyond the daily or total limits, are not rewarded. We may revoke credits obtained through fake sign-ups.
4. Payments and refunds
- Credit packs are paid with WeChat Pay in CNY and credited immediately. There is no subscription and no auto-renewal.
- Credits are digital goods delivered instantly; credits already added are generally non-refundable, except where the law requires otherwise.
- If you were charged twice or your credits did not arrive, contact us with the order number and we will add the credits or refund the payment after checking.
5. What we collect
- Account data: username, password hash, recovery code, and the email address if you choose to provide one.
- Product events: whether you saw the purchase page, which pack you picked and whether you ordered, used only to improve the product and pricing, never including document content.
- Usage records: the time and page count of each export, plus a document key computed from page IDs (used for free re-exports within 24 hours) that contains no image content; credit history; order numbers, amounts and payment status.
- Anti-abuse data: your IP address and a device identifier computed locally in your browser by the open-source FingerprintJS library, used only to limit bulk sign-ups, stacked free exports and fake invites.
- We do not collect your photos, scan previews or exported PDFs.
6. Cookies and local storage
ps_sess: sign-in session (HttpOnly);ps_uid: anonymous visitor ID for invite attribution;ps_ref: the invite code from a link you opened, removed after sign-up.- IndexedDB in your browser stores your scan draft (photos, crops and order), and localStorage remembers your language. This data stays on your device: an exported draft is cleared the next time you open the app, an unexported one after 24 hours, and clearing site data deletes it too.
7. Third parties
Payments are handled by WeChat Pay; we only receive whether an order was paid and the amount, never your card details. The site uses no third-party analytics or ads, and the image engine and fonts are served by this site rather than an external CDN.
8. Retention and your rights
- Daily counters and anti-abuse records are deleted automatically after 90 to 180 days. Account, credit and order records are kept while your account exists.
- You can contact us to access or delete your account data. Unused credits are forfeited when an account is deleted.
9. Disclaimer
Results depend on the quality of your photos; missing or blurry details cannot be recovered. Only scan documents you are entitled to use, and never use the service to forge or alter documents.
