What we collect

We collect the following categories of data when you use Runtake:

• Account data — Your name and email address, collected at sign-up, and your date of birth if you choose to give it. Your name is how Runtake addresses you in the app and in email we send you. Date of birth is optional and is used only to estimate your maximum heart rate for training zones.
• Training data — Planned mileage, activity types, and notes you enter manually into the app.
• Health and fitness data — Completed run data (distance, duration, pace, heart rate, cadence, heart rate zones) synced from Apple Health (HealthKit) on your device, with your explicit permission.
• Strava data — If — and only if — you connect a Strava account, completed run data read from Strava's API: distance, moving time, pace, elevation, average and maximum heart rate, and cadence, including activities you have marked private. Connecting Strava is optional and is offered only when Apple Health has no runs to give us. See Strava data below.
• Location data — Your location, collected in two ways: (1) run location is recorded at the time of a completed workout and stored server-side associated with your account; (2) a default run location may be saved to your account when you explicitly confirm it during manual location setup. Location is also used to display a local weather forecast and is not stored separately for that purpose.
• Training survey responses — Optional post-run survey data including perceived effort (RPE), energy level, and pain notes. Pain descriptions are treated as health data and handled accordingly.
• AI-generated insights — When you request a post-run insight, fitness data from that run is sent to Anthropic's Claude API to generate the insight. See the AI Insights section below.
• Support requests — When you contact support from inside the app, we receive your message along with the email address you give us for a reply, the email address on your account, your account identifier, your app and operating system version, whether Apple Health sync is turned on, and when your device last synced. Those details are what let us answer a report without a round trip. Support messages are delivered to our support inbox and are not stored in your Runtake account.

How we use your data

We use your data only to provide and improve Runtake:

• To display your training plan and completed run history
• To calculate stats such as weekly and monthly mileage totals
• To calculate heart rate training zones from your maximum heart rate and recorded heart rate data
• To send you account email and occasional updates about Runtake
• To show a local weather forecast based on your current location
• To generate AI-powered post-run insights when you request them

HealthKit data

Runtake requests access to Apple Health (HealthKit) to sync your completed workouts. HealthKit data is:

• Read from your device only with your explicit permission
• Stored in your Runtake account database to display your training history
• Never shared with third parties, advertisers, or data brokers, except as described in the AI Insights section below when you explicitly request an insight

You can revoke HealthKit access at any time in Settings → Privacy & Security → Health → Runtake.

Strava data

Apple Health is Runtake's main source for completed runs. Connecting Strava is an optional fallback, offered when your runs are not reaching Apple Health. If you never connect it, none of this applies to you and Runtake never contacts Strava on your behalf.

When you connect, Strava asks you to approve Runtake's access. We request permission to read your activities including private ones, because a runner's own training history is frequently not public. We read only running activities, and only at summary level: distance, moving time, pace, elevation, average and maximum heart rate, and cadence. We do not read your route or GPS trace, your segments, your social activity, or anyone else's data.

Strava-sourced runs are stored in your Runtake account and used the same way any other run is — shown in your training log, counted in your totals, and, if you request an insight for one, sent to Anthropic as described above.

• Disconnecting deletes them. When you disconnect Strava in Runtake, every run that came only from Strava is deleted, along with its pace, heart rate and related data. Runs that also reached us through Apple Health are kept, because Apple Health supplied them independently.
• Revoking access in Strava does the same. If you remove Runtake's access from inside your Strava settings, we delete those runs too, and tell you we have done so the next time you open the app.
• Deleting an activity in Strava deletes it here. Strava notifies us, and we remove our copy.

You can disconnect at any time in Profile → Sync sources on iOS. Runtake is not affiliated with or endorsed by Strava.

AI Insights

Runtake offers an optional AI-powered insight feature. When you tap “Get Insight” on a completed run, the following data is sent to Anthropic (the maker of Claude) to generate your insight:

• Fitness data from that run: distance, pace, heart rate, heart rate zones, and cadence
• Up to 12 weeks of recent training history (distance, pace, heart rate, and run type per run), used as context for the analysis
• If you completed a post-run survey for that run: your survey responses including RPE, energy level, and any pain notes

This data transfer only occurs when you explicitly request an insight — it is never sent automatically.

If you have connected Strava, runs imported from Strava are included in this the same as any other run, both as the subject of an insight and as part of the training history sent for context.

Anthropic does not use API inputs to train its AI models. Your run data is processed solely to generate your insight and is not retained by Anthropic for any other purpose.

For more information, see Anthropic's privacy policy.

Location data

Run location is recorded at the time of a completed workout and stored on our servers, associated with your account. A default run location may also be saved to your account when you explicitly confirm it during manual location setup.

Location is additionally used to fetch a local weather forecast when you view the app. For weather purposes only, your location is sent to a weather service at the time of the request and is not stored separately.

You can revoke location access at any time in Settings → Privacy & Security → Location Services → Runtake.

Third-party services

Runtake uses the following third-party services to operate:

• Supabase — Database and authentication. Your account data and training data are stored on Supabase servers.
• Vercel — Application hosting. Runtake's web app and its API run on Vercel, so requests you make — and the data in them — pass through Vercel's infrastructure.
• Strava — Run import, only if you connect a Strava account. We read your running activities from Strava's API; we never write anything to your Strava account. See Strava data above.
• Resend — Transactional and support email. Your email address is shared with Resend to deliver account email; when you contact support from inside the app, your message and the diagnostics listed above pass through Resend to reach our support inbox.
• Loops — Product and marketing email. When you confirm your email address, your address, your name if your account has one, and your account identifier are shared with Loops. Deleting your account removes your contact from Loops.
• Anthropic — AI insight generation. Fitness data from a specific run, up to 12 weeks of training history, and optional survey responses are sent to Anthropic only when you explicitly request an insight. See AI Insights above.
• Visual Crossing — Weather data. Your current location is sent to Visual Crossing to fetch a local weather forecast. Location is not stored by Visual Crossing beyond the scope of the request.

Data retention and deletion

We retain your data for as long as your account is active. You can delete your account at any time from inside Runtake — on iOS, from Profile, and on the web, from Settings.

Deletion is immediate and permanent. It removes your account along with every run, training plan, race, note, insight and setting attached to it, and removes you from our email list. There is no grace period and no way to recover a deleted account. If you have trouble deleting your account, contact privacy@runtake.app.

Data imported from Strava is additionally deleted when you disconnect Strava, when you revoke Runtake's access from inside Strava, or if Runtake's access to Strava's API ends for any reason. In that last case we will tell you why. Deletions you make in Strava are reflected in Runtake within 48 hours.

Your rights

Depending on where you live, you may have rights regarding your personal data, including the right to access, correct, or delete it. This includes rights under the California Consumer Privacy Act (CCPA) and, for users in the European Economic Area, the General Data Protection Regulation (GDPR). To exercise any of these rights, contact privacy@runtake.app.

Children's privacy

Runtake is not directed at children under 13. We do not knowingly collect personal data from children under 13.

Changes to this policy

If we make material changes, we will update the effective date above and notify users by email where appropriate.
