Records and information

From STILL

STILL records heart rate, breathing, movement, and temperature and humidity under the mattress. After Light brings these together in your sleep records; the environmental readings help show relative changes beneath the mattress.

What you add

You can optionally log your sleep profile, daily habits, and how you feel. Account information includes only your email address and chosen name.

How records are used

Summaries, trends and reports

After Light organizes your recorded nights into sleep summaries, trends, and reports. Any daily notes you choose to add can provide context when looking at patterns across nights.

Ask After Light

Answers draw on the relevant sleep records and your saved profile. Questions about family use only the shared summary, and keeping an eye on an observation requires your confirmation.

Exporting a file does not automatically send it to external AI tools. You choose how to use the exported file.

Family sharing

Sharing between adults

Sharing begins only after an invitation is accepted. Family can see a one-line nightly summary and its update time; opening it shows a few key facts and a short status for six dimensions. For adults, facts include bed exit counts, time to fall back asleep, and sleep duration—not sleep or wake clock times. You can pause or stop sharing at any time.

Guardian-managed profiles

Guardians can create a child’s profile, give consent, and link a STILL in separate steps. A child’s summary can include sleep onset, sleep duration, and wake time; the guardian manages the profile and device.

Family never shows another person’s private trends, raw heart or breathing readings, or daily logs.

Manage your records

In After Light, open Settings › Privacy & data. Your records stay with your account until you delete them.

Export

Request your own data package for download in the app as a ZIP file—it does not include family members’ private data. Free includes saved data at standard detail; Plus also includes recorded second-by-second heart rate and breathing data. Neither plan exports raw signals, and upgrading cannot recover detail that was not previously saved.

Delete

You can delete health and behavior history, or request account deletion. Identity verification and confirmation come before deletion. Deleting your account also ends Family sharing and its link to your STILL.

Email updates

The email address you leave is used only for Right2Rest product and launch updates, kept separate from After Light sleep and health records.

Every update email will include an unsubscribe link. Signing up is not a preorder and involves no payment.
