Privacy Policy
Last updated: July 30, 2026
CardiLog is developed by Speed AI Labs.
Overview
CardiLog is built so your blood pressure readings never have to leave your phone. There's no account to create and no server that stores your health data. This policy explains exactly what that means and what limited information is collected.
Your health data
Every reading you log — systolic, diastolic, pulse, tags, notes, and history — is stored locally on your device using on-device storage. CardiLog does not transmit this data to us or to any third party, does not require sign-up, and does not sync it to any cloud service. If you export a PDF or CSV report, that file is generated on your device and only shared if and when you choose to send it.
Diagnostics and analytics
CardiLog may use standard, anonymized app analytics and crash diagnostics (for example, Apple's built-in App Analytics) to help us understand app stability and general usage patterns, such as which screens are opened or whether the app crashed. This diagnostic data is aggregated, is not linked to your identity, and never includes your blood pressure readings, tags, notes, or anything else you enter into the app.
Third parties
CardiLog is distributed through the Apple App Store, which collects its own standard purchase and download information under Apple's privacy policy. We do not use third-party advertising networks, and we do not sell or share your data with data brokers.
Children's privacy
CardiLog is not directed at children under 13, and we do not knowingly collect information from children under 13.
Your controls
Because there's no account and no server-side copy of your data, you're always in control: export your history as a PDF or CSV at any time, and deleting the app removes its locally stored data from your device.
Changes to this policy
If this policy changes, we'll update the date below. Continued use of CardiLog after a change means you accept the updated policy.
