This page is a curated summary, not a full repost. Campaigns and rewards may change; the official source's current rules prevail. No income is guaranteed.
Suggested steps
- Open the original post and confirm the app name and official link the author recommends.
- Go to the official release page or open-source repo and check that the domain and author match.
- Review the license, privacy notes and whether it is truly offline (any telemetry).
- Confirm supported operating systems and versions, plus installer size and dependencies.
- Download only from the official release channel, verify checksums/signatures, and refuse third-party "cracked" packages.
- Install and test in a non-production environment or a virtual machine first.
- Test opening, editing and exporting (docx/xlsx/pdf/pptx) with a few typical documents.
- Check the result: note layout breakage, missing fonts and other issues to judge whether it covers daily work.
- Fully back up original documents before migrating, and migrate gradually rather than all at once.
- Follow the update channel and security patches; for documents with sensitive data, consider local encryption.
- Features and download data follow the author's release page and the original post at the time.
Cautions
- Beware of fake download sites and bundled software.
- Assess local security and encryption for documents containing sensitive data.
- Format compatibility may lag commercial suites; test important documents first.
