Privacy Policy

Version privacy-policy-v3 · effective 8 September 2026

We built Aspier to help you train smarter — not to sell your data. This page explains exactly what we collect, why, and what control you have over it.

What we collect

Account information

Your email address and display name when you sign up. We use these to identify you and send service emails (e.g. email verification, password resets).

Training and nutrition data

Anything you log in the app — workouts, sets, meals, body weight, photos, sleep, mood. This data belongs to you.

Health data from connected devices

If you connect Apple Health, we read HRV, resting heart rate, sleep, steps, SpO2, respiratory rate and VO2 max to power your recovery and wellness insights. Health data is fetched on-device, sent to our servers over TLS, and stored encrypted at rest. You can disconnect at any time from Profile → Connected Apps.

Diagnostic data

Anonymous crash reports and basic usage analytics (which screens you open, errors you hit) so we can fix bugs and improve the app. No personal training data is included in analytics events.

What we do not collect

• We do not sell your data to anyone — ever.
• We do not share your health data with advertisers, insurers, or brokers.
• We do not access your contacts, calendar, or location unless you explicitly grant a permission for a specific feature.

How we use your data

• Power your features. Generate plans, compute recovery scores, surface insights, etc.
• Improve the app. Debug crashes, prioritise fixes, understand which features are useful.
• Provide support. When you raise a ticket, we look at your account to help.
• Billing. Apple processes payments; we receive subscription status (active / expired) only.

Sub-processors

Aspier uses a small number of trusted service providers to operate the service. Each is bound by a data processing agreement.

• Supabase — database hosting (EU region) and authentication.
• Anthropic — all AI features: training plans and plan adjustments, meal plans, coaching chat, weekly insights, nutrition suggestions and food-photo analysis. Receives your training history, goals, injuries and what you tell it about how training is going.
• Apple — App Store distribution, payments, push notifications, HealthKit.
• Sentry — crash reporting (EU). Receives your account identifier so a crash can be tied to a report; not your workouts, food or messages.
• PostHog — product analytics, off unless you turn it on, and not linked to your account.

Your rights

You can, at any time:

• Export everything. Profile → Account & data → Export my data. You'll receive a JSON file with all your data.
• Delete your account. Profile → Account & data → Delete account. Your data is permanently removed within 30 days. This action cannot be undone.
• Disconnect integrations. Profile → Connected Apps → Disconnect.
• Request a copy or correction by emailing privacy@aspier.app. We respond within 30 days.

Complaints

If you think we’ve handled your data wrongly, you can complain to us. Use the form at aspier.app/complaint/, or email privacy@aspier.app. Tell us what happened and what you’d like us to do.

We acknowledge every complaint within 30 days, usually much sooner, and reply once we’ve looked into it. If we need longer, we’ll tell you why and give you a date.

You can also complain to the Information Commissioner’s Office at any time, whether or not you come to us first. Go to ico.org.uk/make-a-complaint or call 0303 123 1113.

Data retention

Your data stays in our systems as long as your account is active. After you delete your account, all personally identifiable data is removed within 30 days. Anonymous aggregate analytics may persist (e.g. "how many users opened Workout this week") but cannot be traced back to you.

Children

Aspier is not directed at anyone under 18. We do not knowingly collect data from anyone under that age. If we discover that we have, we will delete it.

Changes to this policy

If we make material changes we will notify you in-app and via email. Continued use of Aspier after a change means you accept the updated policy.
