Contact Zerdly
Questions, feedback, a privacy request, or a calculator you’d like us to build? We’d love to hear from you.
Heads up — Zerdly is currently in beta mode. Please bear with us while we get things rolling; we’re actively building, testing and improving, and your feedback genuinely helps shape what comes next.
Email us
The best way to reach us right now is by email. We read every message and aim to reply within a reasonable time.
Suggest a calculator
Zerdly is growing fast. If there’s a calculator, converter or tool you need, email us with what it should do and we’ll consider it for the build queue.
Before you write to us
- We only collect what you put in your message — your name, email and what you write — and we use it to reply and manage abuse.
- Please don’t include sensitive information (health, financial, legal or confidential work details) unless it’s genuinely needed for your request. Email isn’t a secure channel.
- Calculator inputs are never sent to us — they stay in your browser.
See our Privacy Policy for the full detail.
A spam-protected contact form is on the way. For now, please use the email above — there’s no file-upload option at this time.
