Service

Lonely PDF provides on-device PDF reading, local PDF tools, and optional AI assistance. AI answers may be incomplete or incorrect. Always verify important information against the original document using citations.

Your content

You retain rights to PDFs and images you import or create. You are responsible for having the right to use those files with the app and with AI features. Do not upload or process content you are not allowed to use.

Acceptable use

Do not use Lonely PDF to violate law, infringe copyright, harass others, or attempt to attack the AI proxy or related services. Do not reverse engineer or disrupt the service beyond what applicable law expressly permits.

AI features

AI features depend on a network connection and a configured AI server. Availability, model quality, and latency may vary. Snippets sent for AI processing are described in our Privacy Policy.

Limitation of liability

To the maximum extent permitted by law, Lonely PDF and its operators are not liable for indirect, incidental, special, or consequential damages, or loss of data, arising from your use of the app.
