Terms of use.

Effective September 8, 2026

Operator and agreement

PostureKind is operated by MPRR.Co. By using the service or starting a subscription, you agree to these terms and our Privacy Policy. You must be able to enter a binding contract and provide accurate billing information.

Seven-day trial and automatic renewal

Standard includes a seven-day free trial and then costs $3.99 USD per month or $29 USD per year. Pro includes a seven-day free trial and then costs $7.99 USD per month or $59 USD per year. Applicable taxes may be added. Stripe collects a payment method when the trial starts. Unless you cancel before the trial ends, Stripe automatically charges the selected monthly or annual price when the trial ends. Each plan then renews automatically each month or year, according to the selected interval, at the then-disclosed price until canceled.

Cancellation and refunds

You may cancel at any time through the Stripe customer portal opened by the “Manage billing” control on PostureKind. Cancel before the trial ends to avoid the first charge. After billing begins, cancellation stops the next renewal and access continues through the paid period. Except where required by law or stated otherwise at checkout, completed subscription charges are non-refundable. For billing problems, visit Support promptly.

Plan features and changes

Current plan features are listed on the pricing page. We may improve, replace, or discontinue features, but we will not materially reduce a paid plan during its current term without a reasonable remedy. Price changes apply only after advance notice and no earlier than a future renewal.

Health and safety

PostureKind estimates visible pose changes and provides general reminders. It cannot diagnose, treat, cure, or prevent a medical condition; assess spinal compression; determine a uniquely “correct” posture; or tell you whether a movement is safe. Stop using a suggestion that causes symptoms and seek appropriate professional care. Do not let the service delay emergency or medical evaluation.

Camera estimates

Results can be inaccurate because of camera placement, lighting, clothing, occlusion, model limitations, or natural differences between people. Scores are habit indicators, not clinical measurements.

Acceptable use

Use PostureKind only with cameras and devices you are authorized to use. Do not violate another person’s privacy, interfere with the service, evade billing controls, or reverse engineer the service where prohibited by law.

Availability and warranties

To the extent permitted by law, the service is provided “as is” without warranties of uninterrupted operation, accuracy, fitness for a particular purpose, or medical benefit. Mandatory consumer rights are not excluded.

Limitation of liability

To the extent permitted by law, MPRR.Co will not be liable for indirect, incidental, special, consequential, or punitive damages arising from use of the service. Some jurisdictions do not allow particular limitations, so those limitations may not apply to you.

Changes

Material changes will be posted here with a revised effective date. If a change materially affects an active subscription, we will provide notice where required.
