Pulse: Peace of Mind · Last updated 19 June 2026
Pulse is a wellness and peace-of-mind app — not a medical device, monitoring service, or
emergency tool. Data may be delayed or unavailable. Do not rely on Pulse to detect emergencies.
In an emergency, call your local emergency number.
Pulse lets you share a small set of your own Apple Watch wellbeing signals with one specific
person you choose, so a loved one can feel reassured you’re okay — and vice versa. This policy explains
exactly what we collect, why, who can see it, and the control you have. We collect as little as possible
and never use your health data for advertising or to build a profile of you.
Who we are
Pulse is operated by Unlink Media (“we”, “us”). Contact: support@unlinkmedia.com.
The data we collect
- Account. When you sign in with Apple, we receive an Apple-provided user identifier
and, if you allow it, your name and a relay email address. We never see your Apple password.
- Health & activity data — only if you are the person being viewed, and only what you
explicitly choose to share. On your own device, with your permission, Pulse reads from
Apple Health the specific metrics you toggle on — which may include resting heart rate,
sleep, and activity rings. Each metric is off by default and shared only after you
turn it on. If you are only viewing someone else, Pulse does not read your health data.
- Notification tokens. A device token so we can send you app notifications.
- Messages you send. If you send a reaction or message to a person you’re paired with, we store it so we can deliver it to them. You can report a message or block a person at any time, and we act on reports of objectionable content.
- Minimal diagnostics. Basic, non-identifying error logs to keep the app working.
We do not collect your location, contacts, advertising identifiers, or browsing activity.
How Apple Health (HealthKit) data is handled
- Pulse reads Health data only on the device of the person it belongs to, and only
after that person grants permission. There is no way for Pulse to read anyone else’s Health data
from your phone.
- We use Health data solely to provide the Pulse experience to you and the person you chose to
share with — to display your latest values and to compute a personal “usual range” so we
can send gentle, non-alarming check-in nudges.
- We never use Health data for advertising or marketing, never sell it, and never use
it for data mining or to build user profiles.
- We never store Health data in iCloud.
Who can see your data
Your shared wellbeing signals are visible only to the specific person you paired with and only
for the metrics you turned on. Sharing is one-directional per pairing: the person you invited can
see what you chose to share; for them to share back, they make their own choices. You can change what you
share, or stop sharing entirely, at any time — and it takes effect immediately at our servers, not just in
the app. We do not share your data with any other third parties except the infrastructure providers below,
acting on our behalf.
Where your data is stored
Data is stored on our backend provider, Supabase (Postgres + secure functions), and
delivered via Apple Push Notification service. It is encrypted in transit (HTTPS/TLS) and
at rest. Access is restricted by database row-level security so that only you and the person you consented
to share with can read your shared metrics.
How long we keep it, and deleting your account
We keep your latest values and a short trend history while your account is active. You can delete your
account from within the app. When you do, we permanently delete your profile, pairings, consent records,
and stored vitals, and we revoke the Sign in with Apple token associated with your account.
Your controls
- Turn each shared metric on or off, or pause all sharing, at any time.
- Disconnect from a paired person, which immediately stops all sharing in that relationship.
- Delete your account and all associated data.
- Revoke Pulse’s access to Apple Health at any time in the iOS Health app or Settings.
Children
Pulse is not directed to children and is intended for users 17 and older. We do not knowingly collect
data from children under 13.
Changes
If we change this policy we will update the date above and, for material changes, notify you in the app.
