YOUR DATA IS
YOURS. ALWAYS.

Your data is used solely to power the features you see in the app:

• Injection history calculates your countdown timer and schedules reminder notifications
• Weight entries render your trend chart and calculate total change from day one
• Medication data powers the estimated medication level curve using published half-life data
• Dose escalation entries display your personal dosing timeline
• Water log entries display your daily hydration progress
• Side effect notes appear in your private journal
• Progress photos display in your personal photo gallery
• Nutrition entries calculate your daily macro and calorie totals v4
• Bowel health entries display in your private health log and weekly summary v4
• Exercise entries calculate calories burned and update your net calorie budget v4.1
• GLP-1 purpose setting personalises home screen messaging and doctor report context v4.1
• Weekly summary notification assembles a Sunday evening digest from your local data — nothing is sent to any server v4.1

None of this data is used for advertising, analytics, profiling, research, or any purpose beyond what you see on screen.

Glyde optionally integrates with Apple HealthKit. When enabled, Glyde can read and write the following data types:

• Body Mass (Weight): Glyde can import past weight readings from Apple Health and write new entries back
• Dietary Water: Glyde writes your water log entries to Apple Health
• Active Energy / Workouts: Glyde reads exercise calories from Apple Health when enabled (v4.1)
• Dietary Energy & Nutrients: Glyde can import nutrition data from Apple Health (e.g. from MyFitnessPal) v4

This integration is fully optional. You will be prompted to grant or deny permission the first time you use it. You can revoke permission at any time in Settings → Privacy & Security → Health → Glyde.

Glyde does not request, read, or use any other HealthKit data types. All interactions happen locally on your device.

Backup is entirely opt-in and selective. You choose exactly what to include:

• ✓Injections & doses
• ✓Weight logs
• ✓Nutrition entries
• ✓Water entries
• ✓Bowel health entries
• ✓App preferences & settings
• ✕Progress photos — excluded by default (on-device only)

You can initiate a backup or restore at any time from Settings → iCloud Backup inside Glyde. Glyde does not run automatic background backups without your explicit action.

Glyde uses iOS local notifications to remind you when your next injection is due and to prompt your hourly water intake. These are scheduled entirely on your device — they do not pass through any server and do not transmit any health data anywhere.

In Glyde v4, you can configure both injection reminder intervals and water reminder intervals (including custom hourly windows) directly in Settings. None of these preferences leave your device.

You can turn off notifications at any time in Settings → Notifications → Glyde.

Glyde’s optional PIN and biometric lock protects the app on your device. Your PIN is stored locally in iOS UserDefaults. Biometric authentication (Face ID / Touch ID) is handled entirely by iOS’s LocalAuthentication framework — Glyde never has access to your biometric data at any point.

Neither your PIN nor any biometric information is transmitted anywhere, stored in iCloud, or included in any backup.

The only Apple system frameworks Glyde uses are:

• UserNotifications — local injection and water reminders
• HealthKit — optional Apple Health sync (weight, water, nutrition in v4)
• LocalAuthentication — PIN / Face ID app lock
• CloudKit — optional iCloud encrypted backup, including exercise data (v4.1)
• Standard UIKit / SwiftUI frameworks

The USDA FoodData Central database used for nutrition search is accessed at the time you search for food items. Only your search query text is sent to the USDA public API — no personal data, no health data, no device identifiers.

Because Glyde stores all data locally on your device, you are always in complete control:

• Delete individual entries from within the app using swipe-to-delete or the trash icon in each section
• Uninstall Glyde to permanently delete all app data — iOS removes all locally stored data when the app is deleted
• If you have created an iCloud backup, you can delete it from Settings → iCloud Backup inside Glyde, or from your iCloud settings in iOS

Since we hold no data on any server, there is no account to delete and no data deletion request to submit to us.

Glyde is not directed toward children under 13 and we do not knowingly collect information from children. Given that Glyde collects no personal information from anyone, this protection is inherent to how the app is built.

Glyde is a personal logging tool only. It does not constitute medical advice, diagnosis, or treatment of any kind. The medication level estimator uses published pharmacokinetic half-life data to produce an approximation — it is not a clinical tool and must not be used to make medical decisions.

The nutrition tracking feature uses the USDA FoodData Central database for food data. Nutritional values are estimates and may vary. Always consult a registered dietitian for personalized nutrition guidance.

Always consult your licensed physician regarding your GLP-1 medication, dosage schedule, injection technique, and any side effects you experience.

We may update this privacy policy as Glyde gains new features. When we do, we will update the “Last updated” date at the top. Continued use of Glyde after changes are posted constitutes acceptance of those changes.
