Privacy Policy

Pulse: Peace of Mind · Last updated 4 September 2026

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 and current heart rate, sleep, and activity rings and your daily step count. 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.
• Location — only if you turn it on, and only for the people you choose. Pulse has an optional private map. It is off by default. If you switch on location sharing for a specific person, Pulse sends your current location to our backend so that person (and only that person) can see it on their map. You can choose precise or approximate (about a kilometre) location, turn it off for anyone at any time, and turning it off stops collection immediately. We store only your current location while sharing is on; we do not sell it or share it with any third party, and we never use it for advertising.
• 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.
• Diagnostics and crash reports. These are tied to your account so we can find and fix problems you actually hit. They never contain your health readings, your messages, or your location.
• Help & Feedback. If you use the in-app feedback form, we store the category you picked, the text you wrote, whether you said we can contact you back, and basic device/OS/locale info — tied to your account so we can follow up with you.
• Pulse Plus purchase records. If you subscribe, we keep the product you bought, its expiry date, and a transaction identifier so we can unlock the right features on your account. Apple handles your payment — we never see your card details.
• Pairing set-up usage events. We record which set-up steps you completed while pairing with someone (for example, that an invite was created), so we can tell which steps of that flow are confusing and improve them. These events never include any health value, and we never share them with an ad network or any other third party.

We do not collect your contacts, advertising identifiers, or browsing activity, and we do not collect your location unless you explicitly turn on location sharing.

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 13 and older, consistent with its 13+ age rating. 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.
