A real person reads everything sent to this address. Corrections to a calculation get priority and are usually reproduced the same working day.
The fastest route for everything is sophiaanjum05@gmail.com. To help us act quickly, please include the tool name, the exact values you entered, what you expected, and what you actually got. A screenshot helps enormously.
What to write about
- A wrong result. Highest priority. We reproduce, fix and note the change on the tool page.
- A bug or a tool that will not load. Please tell us your browser and version.
- An accessibility barrier. Treated as a defect, not a feature request.
- A tool you wish existed. We read every suggestion; several of the current 106 came from readers.
- Advertising and sponsorship. We sell display inventory only. We do not sell links, reviews or placement inside tool pages.
- Privacy and data requests. See the privacy policy first; if it does not answer your question, write to the same address with "Privacy" in the subject.
Response times
We aim to acknowledge every email within two working days. Reported calculation errors are usually reproduced within one working day, because a wrong number is the one failure we consider serious. We are in the Pakistan Standard Time zone (UTC+5), so replies to messages sent from the Americas often arrive the following morning.
Where we are
We are a small independent team based in Punjab, Pakistan, working in the Pakistan Standard Time zone (UTC+5). We do not operate a public office, so email is the only way to reach us — messages sent from the Americas are usually answered the following morning our time.
Our other site
We also build Open Any File — a free companion site for opening and converting file formats in your browser. It is run by the same team, with the same privacy-first approach.
