PoseTracker API Terms of Use

Welcome to PoseTracker, a service developed by Movelytics SAS. These Terms of Use (ToU) govern your access to and use of PoseTracker, including the tracking API and SDKs, the signed-in assistant at app.posetracker.com, agents you connect through the MCP connector, custom movements, and the service offerings described below. By accessing or using PoseTracker, you agree to be bound by these ToU.

Movelytics SAS reserves the right to modify prices, included features, and limitations of service offerings at any time. These modifications will be effective immediately upon their posting on our website.

Authentication and Security: Access to the PoseTracker API requires authentication via API keys provided by Movelytics SAS. You are responsible for the security of your API keys and any use of the API conducted with these keys.
Usage Restrictions: You agree not to use the PoseTracker API abusively, including attempting to circumvent rate limitations or using the API for illegal activities.

The signed-in assistant at app.posetracker.com (the chat) is provided solely to help you integrate pose estimation and movement recognition through PoseTracker. Permitted uses include embedding PoseTracker in a web or mobile application; customizing parameters, skeleton rendering, colors, overlays, tutorials, or placement silhouettes that consume PoseTracker tracking data; drafting or refining a custom movement to be tracked with PoseTracker; generating integration snippets; and otherwise narrowing a PoseTracker integration toward something you can ship.

The assistant is not a general-purpose development, writing, research, or personal-help tool. You may not use it to develop products unrelated to PoseTracker, to obtain help on technologies or domains outside pose estimation and movement recognition through PoseTracker, or to ask questions that do not serve a PoseTracker integration on web, mobile, or another host application.

Movelytics SAS may refuse off-topic requests, require you to confirm that you intend to build with PoseTracker, and deduct additional AI credits when the assistant is used for purposes other than PoseTracker integration. Continued off-topic use may result in further credit deductions, limitation, or termination of access to the assistant in accordance with these ToU.

Assistant replies, generated snippets, and proposed movement specifications are suggestions. You remain responsible for reviewing them, testing them in your application, and ensuring they are suitable and lawful for your use case. The assistant does not diagnose medical conditions and is not a substitute for a clinician.

The MCP connector (setup, https://mcp.posetracker.com/api/mcp) lets an agent you choose, such as Claude or Cursor, use your existing PoseTracker account after you sign in at app.posetracker.com and click Allow. The same acceptable-use rules apply as for the signed-in assistant.

The agent uses the same assistant, the same AI credits, and the same daily limits as the chat. It cannot create your account and cannot pay. A billing tool only returns a Stripe link that you open and confirm yourself. You can disconnect the agent under Settings → Account → Connected agents. Disconnecting revokes its access.

PoseTracker uses two separate wallets on your account.

Tracking credits. Each metered tracking API call consumes tracking credits (by default 1 credit per call). This is the same metering historically described as “API calls”. Monthly allocations follow the plan published on our website: Free 200, Developer 1,000, Business as agreed. When the wallet is empty, tracking calls are refused until the next monthly refill or an upgrade.

AI credits. The assistant consumes AI credits when it calls a language model to draft or refine a reply or a custom movement. A typical LLM turn costs 1 AI credit.

Some actions cost 0 AI credits: exact-match catalog prompts from the assistant gallery, saving a custom movement, requesting an iframe snippet for a saved movement, toggling preview parameters, and the assistant asking you to mark frames on a local video before any stills are sent. Default monthly AI allocations are 100 on Free, 500 on Developer, and a custom amount on Business. Failed provider calls are not charged.

Daily assistant limits. LLM turns are also rate-limited per calendar day (Europe/Paris midnight): Free 15 turns, Developer 80, Business 200, with a short minimum interval between turns. Movelytics SAS may also pause the assistant when a daily AI spend budget is reached, until the next Paris midnight. Hitting a daily or monthly cap does not refund unused tracking credits.

Monthly wallets are refilled according to your plan. Unused credits do not accumulate unless a written agreement says otherwise. Movelytics SAS may change allocations, costs, and daily limits by updating these ToU or the pricing published on our website. Repeat off-topic use of the assistant may deduct extra AI credits as described above.

You may ask the assistant to draft a custom movement specification for 2D camera tracking. Saving a movement stores a specification on your account so you can embed it with your API key. You remain responsible for the movement you publish in your application.

If you teach a movement from a video, the video file stays on your device. The assistant only receives the still images (and optional pose keypoints) for the 2 to 5 moments you mark. Those images are used for that assistant turn and are not stored as part of the chat history. We may store the number of marks and their timestamps. We do not operate a general file-upload or video-hosting service in the assistant.

Pose estimation on marked frames runs in your browser. Results depend on lighting, framing, and whether the gesture is visible in 2D. Movements that cannot be seen by a single camera may be refused.

Movelytics SAS reserves the right to modify prices, included features, and limitations of service offerings at any time. The prices, features, and limits published on our website apply to new accounts and to new paid subscriptions from the effective date of these Terms of Use.
Paid subscribers already active on that date keep the quotas, price, and features of their then-current plan for as long as their subscription remains active and unchanged. If a paid subscription is cancelled, lapses, or is switched to another plan, the then-published offering applies, including upon any later resubscription.
The Free plan may be updated for all free accounts upon publication on our website.

API Changes: Movelytics SAS reserves the right to modify, update, or discontinue the PoseTracker API or the assistant at any time without prior notice. These changes may affect how you access or use the service.

Movelytics SAS strives to maintain maximum availability of the PoseTracker API but does not guarantee uninterrupted availability.

The PoseTracker API and all content provided through the API are the property of Movelytics SAS or its licensors and are protected by intellectual property laws.

Personal Data Processing: All personal data collected through PoseTracker, including the assistant, will be processed in accordance with our Privacy Policy. Assistant turns may be sent to a third-party language-model provider solely to generate that reply. We do not send your PoseTracker API key to the model.

Copies of all applicable third-party license texts are available upon written request addressed to contact@posetracker.com. Nothing in these Terms of Use limits your rights under, or grants you rights that supersede, the terms of any applicable open-source license. Movelytics SAS makes no claim of ownership over any third-party or open-source components used by PoseTracker, and all respective intellectual property rights remain with their original owners.

Open-Source and Third-Party Models: PoseTracker's pose estimation capabilities may rely, in whole or in part, on third-party and/or open-source pose estimation models (including, for example, MoveNet or BlazePose) and related runtimes, frameworks, or dependencies. Such components may evolve over time and may behave differently across environments.

Mobile Integrations and On-Device Execution: PoseTracker may provide simplified integration methods for mobile applications (including via embedded web views, iframes, or similar approaches). Depending on your integration, pose estimation may run on the end user's device. Compatibility, stability, latency, and accuracy depend on factors outside Movelytics SAS's control, including but not limited to device hardware, operating system version, camera capabilities, available resources, model/runtime optimizations, environmental conditions (e.g., lighting), and (when applicable) network conditions.

Preventive Checks and Integration Assistance: Movelytics SAS may provide integration assistance and/or preventive checks intended to help verify that your application meets certain technical prerequisites for running pose estimation models. These checks are provided on a best-effort basis and do not constitute a guarantee that pose estimation will function correctly, or that outputs will be accurate, stable, or usable on all devices, in all conditions, or for your specific use case.

Your Responsibility: You are solely responsible for testing, validating, and monitoring your integration across your targeted devices and environments, and for ensuring that the pose estimation outputs meet your product requirements and any applicable legal, safety, or regulatory obligations.

Movement analyses, including flexibility measurements and trunk-flexion outputs such as the back flexibility test, are pose-estimation opinions only. They are not a medical device, not a diagnosis, and not a clinical measurement.

In addition to these Terms of Use, analysis data (and feedback data, when that channel exists) carries this notice for the app that reads it: this is a PoseTracker algorithm opinion from pose-estimation data, and it is not a medical or professional opinion. The customer is responsible for any clinical or regulatory use of these outputs.

To the maximum extent permitted by applicable law, Movelytics SAS shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, revenues, data, goodwill, or business opportunities, arising out of or related to your access to or use of the PoseTracker API.
Without limiting the foregoing, Movelytics SAS does not warrant that pose estimation outputs will be accurate, complete, or suitable for any particular purpose, and shall not be responsible for any incompatibility, failure, degraded performance, latency, instability, or inaccurate results of pose estimation on specific devices or environments, including mobile phones, where such issues are attributable to factors outside Movelytics SAS's control (including device limitations or model/runtime optimization constraints).
Movelytics SAS's responsibility is limited to the operation of the PoseTracker API services and the algorithms that process pose estimation data when such data is provided in a correct and exploitable form. If preventive checks are passed but pose estimation outputs remain insufficient, inaccurate, or unusable due to device or model/runtime constraints, Movelytics SAS shall not be liable for such outcomes.

Termination Conditions: Movelytics SAS may terminate your access to the API in case of non-compliance with these ToU. You may also terminate your use of the API at any time.

You agree to indemnify and hold Movelytics SAS harmless from any liability in case of claims arising from your use of the PoseTracker API.

These ToU are governed by the laws of France, and any dispute related to these ToU will be subject to the exclusive jurisdiction of the courts of France.

Movelytics SAS reserves the right to modify these ToU at any time. Modifications will be effective immediately upon their posting on our website.
