Terms of use
Practical terms for using ERITHRA’s online utilities.
Using the tools
Use ERITHRA only for material you have the right to process. You remain responsible for the inputs you provide and for reviewing generated results before relying on them. Do not use the service to violate others’ rights, distribute harmful material, or interfere with service availability.
Files and results
Retain an original copy of important files. Conversion can change metadata, color information, document features, compression quality, or codec characteristics. PDF rewriting can invalidate digital signatures. Browser tools have memory and compatibility limits and may fail on otherwise valid inputs.
No professional advice
Calculators provide mathematical estimates based on your input. They do not provide financial, tax, legal, or other professional advice. Reference exchange rates can differ from transaction rates. Consult an appropriate professional when a decision requires one.
Availability and third parties
Tools are provided as available, without a promise of uninterrupted access or suitability for a particular purpose. External services and browser features can change or become unavailable. Third-party content and libraries remain subject to their respective rights and terms.
Responsibility and updates
To the extent permitted by applicable law, the owner does not accept liability for losses arising from tool output or unavailable service. Nothing here excludes rights or liability that applicable law does not allow to be excluded. These terms may be revised as the platform evolves. Last updated: 29 October 2026.
