Stepdrum Privacy Policy

Stepdrum is in development and is not on the App Store. This is a draft of the policy for its 1.0: the app is designed with no server and no accounts, and to collect no data.

1. The Stepdrum app

Stepdrum is a hand-cranked mechanical calculator made by Ruby Cat for iPhone. “Stepdrum” is a working title; the app’s name on the App Store is not settled.

The app is designed to have no server, no accounts, no advertising and no subscription, and to collect no data. What you set and turn on the machine stays in the app on your phone.

To let you look down on the dials by tipping the phone, the app reads the phone’s motion sensor while it is open. The readings are used at that moment and do not leave your device.

2. This is a draft

This policy was written from the app’s design while the app was being built, before the version that will ship exists. It will be read against that build, and corrected where it differs, before Stepdrum is released. It has not been reviewed as a legal text.

3. Visiting this website

This website is hosted on Cloudflare. Serving and protecting the site involves processing request information such as your IP address, requested URL, request time and browser headers.

Cloudflare Worker logging is enabled, so requests may be logged for site operation. Log retention and access: ask at contact@rubycat.co.

These Stepdrum pages contain no advertising pixels, embedded analytics, forms or remotely hosted fonts. The product page runs a script that moves its drawing of the machine in your browser; after loading its own files from rubycat.co it makes no network requests. The page code does not set cookies or use browser storage.

For information about the hosting provider, see Cloudflare's privacy policy. Following an external link is subject to that site's own practices.

4. Support and privacy requests

If you contact us, your email address, message and any attachments are used to respond to your request. Please do not send passwords or unnecessary sensitive information.

5. Policy changes

Effective date: the day Stepdrum 1.0 is released on the App Store. Until then this page is a draft.

If the app’s data practices change, this policy will be updated.
