Privacy Policy

Last updated: 25 June 2026

1. Who we are

Sharpn (“Sharpn”, “we”, “us”) is a workout and body-tracking mobile application operated by Waleed Alahdal, an individual developer (the “data controller”). If you have any questions about this policy or your data, contact us at support@sharpn.fit.

This policy explains what data Sharpn collects, why, and the choices you have. It applies to the Sharpn mobile app and this website.

2. Information we collect

We collect only what’s needed to run the app and sync your training. This is overwhelmingly data you choose to enter.

Account information

• Email address — to create and secure your account and send password-reset emails.
• Password — never stored in plain text; we keep only a one-way bcrypt hash.
• Display name (optional).

Profile & fitness goals

• Fitness goal, starting weight, target weight, target body-fat, and target date.
• Height, year of birth, and biological sex — used to personalize estimates (e.g. calorie calculations) and goal tracking.

Body metrics & measurements

• Body weight, body-fat percentage, and muscle mass entries over time.
• Body measurements you log (e.g. neck, chest, waist, hips, arms, thighs, calves).

Workout data

• Workouts, exercises, and sets (weight, reps, RPE, duration, distance), routines/programs, personal records, and custom exercises.
• Any notes you add, and any photos you optionally attach to a workout.
• App preferences (units, rest defaults, reminders, theme, progression settings).

Health app data (optional)

If you turn it on and grant permission, Sharpn can read body data (such as weight and body composition) from Apple Health (HealthKit) on iOS or Health Connect on Android, to save you from re-entering it. This access is entirely opt-in and can be revoked at any time in your device settings. See Section 3.

What we do not collect

• No advertising identifiers and no third-party advertising or analytics SDKs.
• No precise location tracking.
• In-app diagnostic/debug logs (when you enable them) stay on your device and are not transmitted to us.

3. Health & fitness data

Body metrics, measurements, and any data imported from Apple Health or Health Connect are treated as sensitive health and fitness information. We commit that:

• Health data is used only to provide the app’s features to you (tracking, charts, goals).
• We will never use health data for advertising or marketing, and we will never sell it or share it with data brokers.
• Data obtained through Apple Health is handled in line with Apple’s HealthKit requirements; data obtained through Health Connect follows Google’s Health Connect requirements.

4. How we use your data

• To create your account and authenticate you.
• To store, back up, and sync your training and body data across your devices.
• To calculate progress, trends, personal records, and goal estimates.
• To send transactional emails you request, such as password resets.
• To maintain security, prevent abuse, and fix bugs.

We process this data to perform the service you’ve asked for and, where applicable, on the basis of your consent (which you can withdraw).

5. Storage & security

• Your data is stored in a PostgreSQL database hosted by our cloud provider (see Section 6).
• All traffic between the app and our servers is encrypted in transit using HTTPS/TLS.
• Passwords are stored only as salted bcrypt hashes.
• Authentication tokens are kept in your device’s secure storage (Keychain on iOS, Keystore on Android).
• A copy of your data is also cached on your device so the app works offline.

No method of transmission or storage is 100% secure, but we take reasonable measures to protect your information.

6. Service providers

We use a small number of trusted providers to operate Sharpn. They process data only on our behalf:

Provider	Purpose	Data involved
Railway	Cloud hosting & database	Account and fitness data
Resend	Transactional email (e.g. password reset)	Email address
Cloudflare	DNS & website delivery	Standard web request data
Apple / Google	App distribution & optional health integrations	Per their own policies

7. Sharing & disclosure

We do not sell or rent your personal data. We only disclose data:

• To the service providers above, strictly to run the app.
• If required by law, regulation, or valid legal process.
• To protect the rights, safety, or property of Sharpn or its users.

8. Data retention

We keep your data for as long as your account is active. When you delete your account, your associated personal and fitness data is permanently removed from our systems (backups are purged on a rolling basis). You can also delete individual entries in the app at any time.

9. Your rights & choices

• Access & correction — view and edit your profile and entries directly in the app.
• Export — your workouts and body data can be exported/backed up from the app.
• Deletion — delete individual records in-app, or request full account and data deletion (see below).
• Withdraw health access — revoke Apple Health / Health Connect permissions in your device settings at any time.

To delete your account and all data, use Profile → Delete account in the app, or email support@sharpn.fit from your account email. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA; contact us to exercise them.

10. Children

Sharpn is not directed to children under 13 (or the minimum age required in your country), and we do not knowingly collect data from them. If you believe a child has provided us data, contact us and we will delete it.

11. International users

Sharpn is operated from the Kingdom of Saudi Arabia and uses cloud providers that may process data in other countries. By using the app, you understand your data may be transferred to and processed in locations with different data-protection laws than your own.

12. Changes to this policy

We may update this policy as the app evolves. We’ll revise the “Last updated” date above and, for material changes, provide a notice in the app or by email.
