Found a bug, have an idea for a sixth challenge, or a question about privacy? Send us a note.
We read every message, though we can't promise an instant reply. Most emails get an answer within a few working days.
What to write about
- Bug reports. Something didn't load, a tap didn't register, or a score looks wrong.
- Challenge ideas. Suggestions for new challenges or tweaks to the current five.
- Accessibility. Anything that makes Pulse hard to use with a screen reader, keyboard or other assistive technology.
- Privacy questions. How the site handles data, or a request about an email you've sent us.
- Partnerships and press. Business enquiries, features and interviews.
Reporting a problem
To help us fix things faster, please include:
- your device and operating system, for example an Android phone or a Windows laptop;
- your browser and its version;
- which challenge you were on and what you expected to happen;
- a screenshot, if you can take one.
Before you write
- My best score disappeared. It's stored only in your browser, so clearing site data, using a private window or switching devices will reset it.
- Can I see how I compare with others? No. Pulse doesn't collect results, so there are no leaderboards or percentiles.
- My reaction time seems slow. Screen refresh rate, touch latency and browser load all add a few milliseconds. Compare runs on the same device.
- How do I stop notifications? Open your browser's site settings for this page and set notifications to Block.
More detail is on the About and Privacy pages.
