Privacy Policy

Last updated: September 16, 2026

The short version

Paper Saver does not collect, store, or share any personal information. There are no accounts, no analytics, no advertising, and no tracking.

What stays on your device

Everything you put into the app — the PDFs you save, their titles, tags, categories, reading position, and extracted text — is stored locally on your device.

If you use iCloud sync, this data also syncs through your own private iCloud account, which only you can access. It is stored under your Apple ID, not on any server operated by the developer. The developer cannot see it.

What leaves your device

Three things, none of them personal:

1. When you search, your search terms are sent to PubMed (operated by the US National Library of Medicine) and to Crossref in order to return results. No identifying information is attached to these queries.

2. When the app identifies a paper, it sends that paper's DOI — a public identifier printed in the document — to Crossref and to Unpaywall to retrieve its title, journal, authors, year, and whether a free, openly licensed copy exists.

3. When you choose to save an open-access paper, the app downloads that PDF from the repository or publisher that has made it openly available. The app does not send your library, your reading activity, or the contents of your PDFs anywhere.

No personal information is included in that request, and the contents of your PDFs are never uploaded.

AI features

The app's tag and category suggestions run entirely on your device using Apple Intelligence. Your papers are not uploaded to any AI service, and these features work offline.

Sharing

When you use the share feature, the PDF is handed to whichever app you choose (Mail, Messages, AirDrop, and so on). What happens to it after that is governed by that app's own privacy policy.

Children's privacy

The app collects no personal information from anyone, including children under 13.

Changes

Any future changes to this policy will be posted on this page with an updated date.
