Your Content
You keep ownership of the PDFs, notes, annotations, metadata, evidence, exports, and project material you put into Papyrus. You are responsible for making sure you have the right to store, process, annotate, export, sync, or share that material.
Papyrus can help organize citations and metadata, but you are responsible for checking source documents and exported citations before relying on them in academic, professional, legal, medical, financial, engineering, or publication contexts.
Storage, Sync & Third-Party Services
Papyrus stores your library locally unless you choose to export, share, or configure sync. Optional sync can use Apple's iCloud / CloudKit services under your Apple ID, a WebDAV server and folder you provide, or both. You are responsible for the security, availability, retention, and access controls of any Apple account, server, or storage provider you connect.
Metadata enrichment may contact public scholarly services such as Crossref, arXiv, Semantic Scholar, OpenAlex, OpenLibrary, NCBI / PubMed / PMC identifier services, Zenodo, and doi.org. Those services have their own terms, rate limits, privacy practices, and availability.
Acceptable Use, Warranty & Liability
Do not use Papyrus to violate law, infringe rights, evade access controls, overload third-party services, or sync or share material you are not permitted to handle. Keep your Apple ID, WebDAV credentials, and exported files secure.
Papyrus is provided as-is to the fullest extent permitted by law. The developer does not guarantee uninterrupted operation, perfect metadata extraction, compatibility with every PDF, or availability of third-party services. To the fullest extent permitted by law, the developer is not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or goodwill.
Changes & Contact
These terms may be updated as Papyrus changes. Material updates will be reflected on this page with a new last-updated date.
