These terms cover your use of TennisSwing AI, a swing analysis service run by 4Devlabs. Using the service means you accept them.
You upload side-view video of your tennis swings. We detect contact points, map racket swing paths, and return review overlays and reports. It is an analysis aid, not coaching, and results depend heavily on the angle, lighting and framing of what you upload.
You sign in with Google. You are responsible for activity under your account and should not share it.
You keep ownership of the video you upload. You confirm you have the right to upload it, and that anyone identifiable in it is content for it to be processed. You grant us only the permission needed to store and analyse it and return results to you. See the Privacy Policy for how long we keep it, and Delete account for removing it.
Free accounts include a limited number of analyses per month. Pro plans lift that limit. Prices are shown before you pay. Payments are handled by Paddle, who act as the merchant of record, and their terms apply to the transaction itself.
Refunds are covered by our Refund Policy.
Do not attempt to break, overload or work around the service, including its usage limits, and do not upload anything unlawful or anything you do not have the right to. We may suspend an account that does.
We aim to keep the service running but do not guarantee uninterrupted availability. It depends on third-party infrastructure and on the quality of what you upload. The service is provided as is, without warranties beyond those the law requires.
To the extent the law allows, 4Devlabs is not liable for indirect or consequential loss arising from your use of the service. Nothing here limits liability that cannot be limited by law, and your statutory rights as a consumer are unaffected.
You can stop using the service at any time, cancel a paid plan, and ask us to delete your account — see Delete account. We may suspend or close an account that breaches these terms.
We may update these terms. The effective date above will change. Continuing to use the service after that means you accept the update.
