The short rules

Pulse exists to help two people support each other. Health data is the most personal information we will ever touch, so we built the app around one rule: your raw biometric data never leaves your device.

1. Who is responsible

Knightify FlexCo, Rauchgasse 28 Top 2, 1120 Vienna, Austria. Reach the data protection officer at [email protected].

2. What stays on your device

The following is read from Apple HealthKit, processed locally on your iPhone, and never transmitted to our servers or your partner:

  • Resting heart rate, heart rate variability
  • Sleep duration and sleep stages
  • Steps, exercise minutes, standing hours
  • Respiratory rate, mindfulness sessions
  • Menstrual cycle data (only if you enable Rhythm Awareness)

3. What we send to your partner

Once your iPhone has interpreted your day against your own rolling baseline, it generates a single, human-readable cue, for example, “A calm evening might mean a lot today.” Only the cue and a small set of suggested actions are synced through Apple’s iCloud private/shared database to your partner.

5. Lawful basis (GDPR / DSG)

We process data on the basis of your explicit consent (Art. 6(1)(a) GDPR, complemented by the Austrian DSG) for health-related signals, and on the basis of contract performance (Art. 6(1)(b)) for account management. You can withdraw consent in Settings → Privacy at any time.

6. Your rights

  • Pause sharing for an hour, a day, or forever.
  • End the connection, every shared cue is deleted from iCloud.
  • Download your data as a single JSON file.
  • Request deletion of your account at [email protected].
  • Lodge a complaint with a supervisory authority (DSB in Austria, your local DPA in the EU).

7. Retention

Shared cues expire at the end of the calendar day and are removed from iCloud automatically. Your account record is kept while your subscription is active, then deleted within 30 days of cancellation.

8. Sub-processors

Apple iCloud (sync & storage of wellness cues, EU region), Stripe (payments, your payment data is not stored by us), Fastmail (support email). No advertising, analytics, or attribution providers.

Terms of use

Effective · 19 May 2026 · Governing law · Austria

1. What Pulse is, and is not

Pulse is a wellness companion. It is not a medical device, diagnostic tool, or substitute for professional health advice. The cues Pulse generates are suggestions, not statements of fact, and use language like “might” and “could” for that reason.

2. Account & eligibility

You must be 18 or older to use Pulse. You are responsible for keeping your Apple ID and device secure. One account per person.

3. Subscription & payment

Pulse is offered as a paid subscription. Payment is handled through the Apple App Store or our website (Stripe). You can cancel any time; the subscription stays active until the end of the paid period.

4. Acceptable use

  • Do not use Pulse to monitor someone without their continuous, informed consent.
  • Do not attempt to reverse-engineer the on-device interpretation models.
  • Do not use Pulse in any safety-critical or medical context.

5. Liability

To the extent permitted by Austrian law, Pulse is provided “as is”. We are not liable for relationship outcomes, missed cues, or decisions made based on a wellness suggestion. Our total liability is limited to the fees you paid in the previous twelve months.

6. Termination

You may delete your account at any time. We may suspend accounts that violate these terms, with notice where possible.

7. Jurisdiction

Austrian law applies. Exclusive place of jurisdiction is Vienna, Austria, without prejudice to mandatory consumer protection in your country of residence.
