Privacy Policy

Who we are

Stride & Strength is published by Linkstars, LLC. Contact: support@stridenstrength.com.

What we collect

Account details: your email address and password (stored securely by our authentication provider, Supabase).
Fitness and nutrition records you enter: workouts, runs, meals, weigh-ins, water logs, goals and profile details such as height, age and training preferences.
Sensitive profile information: if you choose to enter them, your pregnancy or breastfeeding status (used to set nutrition targets) and your cuisine preferences (used to suggest meals). This information is used only to personalize the app for you.
Private progress photos: photos you choose to upload to My Transformation. These are stored in a private, per-user folder, encrypted at rest, and only your signed-in account can view them, through short-lived links. We never view your progress photos.
Photos you send for analysis: meal, equipment and run photos you submit for AI estimates are sent to our AI provider to produce the result.
Strides Pro status: if you start the free month or subscribe, we store your trial start date and subscription status so Pro works on every device you sign in to.
AI usage counts: how many AI requests your account made this month, so free-account limits can be applied fairly.
Browser data: preferences and unsaved drafts are kept on your device.

Error reports

When something goes wrong in the app (an error, or the app closing unexpectedly), it sends a short anonymous report to our own database so we can fix it. No outside crash or analytics company is involved. A report contains the error message and where in the app's code it happened, the app version, your device type and how long the app had been open. It contains no name, email, account ID, health, food, workout or photo information, and it is not linked to your account. Emails, IDs and web-address details are removed from the error text before it is sent. Reports are not used for advertising or tracking and are deleted after 60 days.

How we use it

We use your information to provide the app: to sync your records across devices, generate estimates and plans you request, and show your progress. We do not sell your personal information and do not use it for advertising.

Service providers

Supabase: account authentication, the database and private photo storage.
OpenAI: processes the meal, equipment, run and plan requests you submit. Content sent to the AI service is used to produce your result.
Apple, Google and Stripe: process subscription payments when available. They share your subscription status with us, not your card details.
Netlify: hosts the app and runs its server functions.

Strides Pro, free trial and purchases

Strides Pro is an optional subscription. Starting the one-month free trial needs only a free account, not a card. When subscriptions are available, purchases are processed by Apple (App Store), Google (Google Play) or Stripe (website). We receive confirmation of your subscription status, never your full card number. See our Terms of Use.

Health information

Stride & Strength is a tracking tool, not a medical service. Estimates and plans are approximate and are not medical advice. Talk with a qualified professional before starting a new exercise or nutrition plan.

Apple Health

If you turn on Apple Health in the iOS app, Stride & Strength reads your workouts, steps, active calories, body weight, resting heart rate, heart rate variability and sleep. It writes only the workouts you log in the app. This data is used only to show your activity and recovery in the app and in your account. It is never sold, never used for advertising, and never shared with third parties. You can change access at any time in the Health app or iOS Settings.

Affiliate links

Some shopping links in the app are affiliate links (Amazon Associates). If you buy something after tapping one, we may earn a small commission at no extra cost to you. No personal health data is shared with Amazon. Only the item search text (for example, "rice") is sent, and only when you tap a link.

Kroger

You can choose to connect your Kroger account from the grocery list. We use the connection only to search Kroger products near your ZIP code and to add items to your Kroger cart when you tap "Add to Kroger cart". Your Kroger sign-in tokens are stored in a secure, encrypted cookie on your device, not in our database, and are never readable by the app's page code. You can disconnect any time:

Your choices

Export: download a backup of your records from the Progress section.
Delete: you can delete your account and its cloud records and photos from the Cloud account section of the app. See the section below.

Deleting your account

Sign in, open the Cloud account section, and choose Delete account. This permanently removes your account, your cloud records and your private photos. Records saved only on your device stay on that device until you clear the browser’s data. If you cannot sign in, email support@stridenstrength.com and we will help.

Children

The app is not directed to children under 13, and we do not knowingly collect their information.

Changes

We may update this policy. The date at the top shows when it last changed.
