Sleep Schedule Privacy Policy
Updated: September 14, 2026
What Sleep Schedule does
Sleep Schedule estimates bedtime and wake-up times using 90-minute sleep-cycle calculations. It does not provide medical advice, diagnose conditions, or measure sleep stages.
Website analytics
This Thoughtbubble website uses Umami to measure anonymous pageviews and interactions, such as opening an app, choosing a store, reading a blog, or using a demo. Events include limited product, platform, and source context so we can understand which pages and links are useful.
Website analytics do not include your files, pasted text, reading content, search terms, sleep times, or other personal inputs. Page and link addresses are recorded without URL query strings or fragments. We do not send account identities or persistent device identifiers with these events.
The analytics service receives ordinary connection information, including IP address and browser information, to produce aggregate visitor and device reports.
This disclosure covers the website, including its portfolio pages, product landings, blogs, and demos. The apps and external services linked here have their own privacy policies.
App analytics
Current app versions send limited product analytics to our self-hosted Umami service, including actions, platform, app version, and whether an action succeeded. A random identifier belongs to this app installation and links first and repeat use. It is separate from advertising and hardware identifiers and is not linked to website visitors or other apps. Analytics do not include your chosen sleep or wake times. A local queue holds up to 100 events for up to seven days while delivery is unavailable.
Information stored on your device
Your preferences, such as time format, preferred cycle count, and fall-asleep delay, are stored locally on your device. Sleep Schedule does not send those preferences to a Thoughtbubble server.
Calendar exports
When you choose to add a sleep estimate to your calendar, the app creates a calendar file locally for you to review and import. The file is not uploaded to Thoughtbubble.
Children’s privacy
Sleep Schedule is not directed to children under 13, and we do not knowingly collect information from children.
Changes and contact
We may update this policy when the app changes. Questions about this policy can be sent to [email protected].
This policy applies to the Sleep Schedule app published by Thoughtbubble with package name com.thoughtbubble.sleepschedule. The website analytics section covers this website.
