What stays on your device

Claptoscore runs entirely in your browser. Your taps, recordings, settings and calibration are processed locally and stored only in your browser's local storage, so they are there next time you visit. They are never sent to us. You can remove them at any time by clearing this site's data in your browser.

If you turn on the microphone, the audio is analysed in real time on your device to detect claps. It is not recorded, stored or transmitted. The microphone switches off when you untick the option or close the page.

If you switch on MIDI in, your browser asks permission to use your MIDI devices. The notes you play are read on your device as taps and are not stored or transmitted.

Shared rhythm links

When you press Share, your browser packs the written rhythm (meter, tempo, the notes and the name you give it) into the link itself. Nothing is uploaded at that moment. When someone opens the link, the rhythm travels as part of the web address: our server reads it to build the page and its preview picture, and it appears in the short-lived logs described under Hosting, like any other page address. Please do not put personal details in the name. Scores from clapping a shared rhythm stay on that device unless you copy and send them yourself.

Hosting

The site is served through Amazon Web Services (Amazon S3, CloudFront, and AWS Lambda for shared rhythm pages). Like any web server, these services process your IP address and request details to deliver the pages and may keep them in short-lived logs for security and operations.

Fonts are loaded from Google Fonts and the notation library from cdnjs (Cloudflare); these providers receive your IP address when your browser fetches those files.

Advertising

Claptoscore is free and is funded by advertising. Ads are provided by Google AdSense. Google and its partners may use cookies or similar technologies to show ads, measure them and, where you consent, personalise them based on your visits to this and other websites. Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent through a Google-certified consent tool before any personalised advertising, and can change their choice at any time through the privacy link it provides.

You can learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites, and opt out of personalised advertising at adssettings.google.com.

Claptoscore Pro

Pro is sold through Stripe, which processes your payment and billing details under its own privacy policy. We see the order in our Stripe account (including your name, email address and country) and use it only to handle your purchase, refunds and support, and to meet our tax and accounting obligations.

Your licence key is derived from your Stripe payment. When you activate Pro, our server checks with Stripe that the payment succeeded and has not been refunded, and records a random id for each browser that uses the key (at most three), together with the payment's id. No name, email address or card details are stored on our server; its logs record technical errors only and are deleted after 14 days. The key and a signed token are stored in your browser's local storage and checked again about once a week. Deactivating Pro on the Pro page removes it from your browser and deletes that browser's id from our server.

Saved takes stay in your browser, like everything else you record.

Tips

If you choose to leave a tip, it is handled by Ko-fi and its payment provider under their own privacy policies. We see the name, email address and message you give there, and use them only to thank you and to meet our tax and accounting obligations.

Your rights

Because we do not collect personal data ourselves, there is usually nothing for us to show, correct or delete. For data held by Google in connection with ads, use Google's own tools linked above. Under the GDPR you may also lodge a complaint with your local data protection authority.
