Privacy Policy

We collect only what the app needs to function. There are two tiers depending on whether you create an account.

Without an account (offline mode)

Everything stays on your device. No data leaves it:

• Workout sessions, sets, reps, weight, and duration
• RPE (Rate of Perceived Exertion) ratings you log
• Body metrics you enter in Profile (age, height, weight)
• Heart-rate zone configuration
• Equipment profile and training preferences

With an account (optional cloud sync)

When you sign in, the following is stored on our servers so your history syncs across devices and is visible to any coach you connect with:

• Email address — used to identify your account
• Workout history — all sessions, sets, reps, weight, duration, RPE, and heart-rate data you log
• Coach-client link — if you accept an invite from a coach, a record linking your account to theirs is stored

We do not collect your name, phone number, location, or payment details for the workout-tracking app itself.

Apple Health

With your permission, Pillar can read resting heart rate and max heart rate from Apple Health to personalise your HR zones, and write completed workouts back so they appear in the Fitness app. This data is processed on-device only — it is never sent to our servers.

We use your data for one purpose: making the app work for you.

• Workout history — to display your past sessions, compute personal records, and show progress charts
• Email address — to authenticate you and, if you contact us, to respond
• Coach-client link — to let a coach you have connected with view your sessions and send you programs

We do not use your data for advertising, profiling, or sale to third parties — ever.

If you accept an invite from a coach, they gain read access to your full workout history — including sessions logged before the day you connected. This is intentional: coaches need historical context to program effectively.

The invite confirmation screen in the app states this clearly before you accept. You can disconnect from a coach at any time in Profile → Connected Coaches. Disconnecting immediately revokes their access; your history remains on your account.

Coaches do not have access to your Apple Health data, your device location, or any data you have not logged through Pillar.

Our database (Supabase) runs on AWS infrastructure in the United States. By creating an account you consent to your data being stored there.

We do not embed analytics SDKs, advertising networks, or tracking pixels.

Your data is retained for as long as your account exists. You can request full deletion of your account and all associated data by emailing privacy@pillarworkouts.com. We will process the request within 30 days and confirm by email when complete.

Workout history you export (CSV or backup JSON) is your copy to keep or delete independently.

Pillar is not directed at children under 13. We do not knowingly collect personal information from anyone under 13. If you believe a child has created an account, contact us at privacy@pillarworkouts.com and we will delete it promptly.

If we make material changes — changes that affect what data we collect or who can see it — we will update the effective date at the top of this page and notify signed-in users by email at least 14 days before the change takes effect. Continued use of the app after that date constitutes acceptance.
