Terms of Use

Using the tools

Letvr Tools is free to use for personal and commercial purposes. You do not need an account, and you keep all rights to the files and text you process — they never leave your device.

Last updated: 2026-09-28.

Results are provided as-is

The tools are carefully tested, but they are provided "as is", without warranty of any kind. Check important results before relying on them, and keep your original files: a tool that rewrites a PDF or converts a spreadsheet produces a new file and never modifies the one you opened, but you are responsible for choosing which copy to keep.

Calculator results are estimates for planning and comparison. They are not financial, legal, tax or medical advice. Real loans and investments involve fees, taxes, insurance and changing rates that a general-purpose calculator cannot know about; confirm figures with your lender, adviser or the relevant contract.

To the extent permitted by law, the operator of this site is not liable for any loss or damage arising from the use of the site or its tools.

Acceptable use

Use the tools only with files and data you are entitled to process. Do not use the site to break the protection on documents you are not authorised to open. Automated scraping of the site at a volume that affects other visitors is not permitted.

Content and third-party software

The explanations, guides and design of this site are the work of its author. The tools use open-source libraries, including pdf.js (Apache License 2.0) and pdf-lib (MIT License); their licences are reproduced in full at /third-party-notices.txt. Product names such as Microsoft Excel and Adobe Acrobat are trademarks of their respective owners and are mentioned only to describe compatibility.
