Terms of use
Last updated 1 November 2026
- Qaren is free while it is in beta, with no sign-up.
- Its results are for you to check before you rely on them.
- Upload only data you are allowed to use, and don't try to overload or break the service.
The service
Qaren, by AnaFiles, compares two lists: it pairs their rows by a key column and shows the rows that are new, removed or changed, and the keys used more than once. It is offered free of charge during a beta period, without an account. We may change it, limit it, pause it or end it at any time. If we introduce accounts or paid plans, we will announce it on the home page before it applies.
Check the results
The comparison is automatic. It can pick the wrong header row, pair the wrong columns, read a date with day and month the wrong way round, or treat two values as the same that you would call different, especially in unusual files. Every choice is shown so you can change it, and both lists are kept in the Excel file. The results are for a qualified person to review. They are not accounting, audit, tax or legal advice.
Your files
Your files stay yours. You give us permission to process them only to compare them for you, as described in the privacy page. You confirm that you are allowed to upload them.
Fair use
To keep the tool free and fast for everyone, there are limits on file size, rows per list and uses per hour and per day, and a comparison is stopped if it runs too long. Don't try to get around the limits, run automated or bulk requests, probe for weaknesses, or upload anything harmful.
No warranty
The service is provided "as is" and "as available", without warranties of any kind, to the extent the law allows. To the extent the law allows, AnaFiles is not liable for any loss arising from use of the service or reliance on its results, including lost profits or data. Nothing in these terms limits liability that cannot be limited by law.
Law
These terms are governed by the laws named by AnaFiles in a future update of this page. Until then, the law of the place where AnaFiles is established applies.
