Millis: Reaction Time Test is built so that your data stays with you. This page explains, in plain language, what the app does and does not do with your information.
Nothing is sent to us. Everything you enter in Millis: Reaction Time Test is stored locally on your device. We do not run user accounts, we do not have a server that receives your entries, and we do not use third-party analytics or advertising SDKs.
If you use the share or export feature, the content you choose leaves the app only to the destination you pick (Messages, Mail, Files, etc.). We do not receive a copy.
Your data lives only on your device. Deleting the app deletes all of its data. Device backups (iCloud, Google) may include app data according to your own backup settings.
Millis: Reaction Time Test is not directed at children under 13 and does not knowingly collect information from them.
If the app ever starts collecting data in a new way (for example adding crash reporting), this page will be updated first and the date above will change.
