Privacy & your data FAQ

Your browser also keeps the 6 most recent clips on the device, so you can re-analyze one without uploading it again. Those copies do not leave the device either.

When you are signed in, a saved analysis can include one still frame used to draw your swing trace, and it syncs with the analysis; deleting the analysis removes it. Beyond that, two optional features can send part of a clip: a limited set of still frames, never the full video. Both only run if you choose them — a cloud re-read offered when your device could not read the footage, and an "AI second opinion" you can start from the One Fix step of your results. See what leaves your device.

The upload screen offers an optional, unticked "Help improve SwingVantage" box, only to a signed-in adult filming themselves and only with the app set to English. If you tick it, we keep a copy of that video, visible only to the SwingVantage team, to train and test our own swing-analysis models until you withdraw or 3 years after your last shared upload. If you do not see the box, or leave it unticked, your video is not kept for training. See videos you choose to share for training.

Motion Lab saves each analysis in the browser that made it. When you are signed in, your recent analyses are also kept with your account so they follow you to other devices. They carry the reads, a compact motion track and, for some swings, one still frame used to draw your swing trace — never the video file. A "Sync your swing analyses" switch in Settings can also keep a separate backup copy of each analysis in your account, with a short summary of how well the read held up. See syncing across devices.

Until you create an account, your data lives only in that browser, so clearing its storage, or switching to another browser, leaves it behind.

Two optional features can send a limited set of still frames from a clip, never the file itself, and each analysis sends a short anonymous reliability record that is not linked to your account — see what leaves your device. If SwingVantage offers you the optional training box and you tick it, a copy of that video is stored for training; see training on your video. Either way the data is yours to download or delete.

• One session: remove it from your sessions list. There is a short undo window.
• Everything, but keep the account: Reset All Data in Settings → Data Management deletes your profile, clubs, sessions and swing analyses from this device and, when you are signed in, from your account on every device.
• This device only: Clear Data On This Device, in the Data Center, wipes SwingVantage from this browser. Your account copy stays, and signing in brings it back.
• The account itself: see deleting your account.
• A video you shared for training: "Stop using my videos for training" in My Data withdraws your consent and deletes every video you shared. Deleting your account deletes them too.

Resetting everything and deleting the account both ask you to type a confirmation word first, because neither can be undone.

Before you create an account your data is only in your browser, so clearing the browser's storage removes it. For anything you cannot delete yourself, email privacy@swingvantage.com.

• A reliability record for every analysis attempt, whatever your cookie choice and whether or not you are signed in: the sport and kind of swing, how usable the clip was, which parts of the report could not be produced, whether the analysis finished, failed or was cancelled (with a short failure code), how long it took and how much of the visual proof held up — plus your device type, browser, operating system and a random code for this browsing session. It contains no video, frames, body positions, name, email or account ID. The same anonymous channel reports app errors.
• Account sync, when signed in: your profile, sessions, progress and recent swing analyses — the reads, a compact motion track and, for some swings, one still frame used to draw the swing trace. Never the video file. If you turn on the "Sync your swing analyses" switch, a separate backup copy of each analysis and a short summary of how well the read held up are added.
• The cloud re-read, only if you agree: up to 60 still frames from a clip your device could not read.
• The AI second opinion, only when you start it: a small sample of still frames, processed by a third-party AI provider where that review is available.
• A video you choose to share for model training. The upload screen offers an optional, unticked "Help improve SwingVantage" box, only to a signed-in adult filming themselves and only with the app set to English. If you tick it, a copy of that video is kept for the SwingVantage team until you withdraw or 3 years after your last shared upload. Without that tick, no video is kept for training.
• AI Coach, when you ask it something: your question and the sport. When you are signed in it also sends what it answers from — profile details such as your first name, level, handedness or batting side, usual miss and goal, your latest result and your three most recent ones (main issue and score, plus launch-monitor numbers for golf), the One Fix you are working on (its title, cue and drill) and your coaching style. Not your video, and your email and account identifiers are not passed to the AI provider.
• Questions you type into Ask, and a launch-monitor photo you ask SwingVantage to read.
• A launch-monitor CSV whose key columns SwingVantage cannot recognize: its column names and up to 8 sample rows are sent automatically so an AI service can suggest the column mapping. The import preview also has a "Re-read my file with AI" button that sends the same.
• Usage analytics: tools that set cookies follow your cookie choice, while cookie-free counts of page views and page speed are collected whatever your choice.

Who processes each of these is covered in third-party services.

Clips your device read well are never sent. The offer also only appears where the cloud service has been set up, so you may never see it.

Before anything is sent, you confirm that frames will leave your device and that the result is still an estimate, not a measurement. It also checks the athlete’s age as set in your settings (adult or under 18). A young athlete needs a parent or guardian’s consent on file, and if the athlete’s age is unknown the cloud read cannot be used. Staying on-device is always one tap away.

SwingVantage’s server passes the frames on for that read without storing or logging them. Often a better recording helps more — the quality tiers tell you what to change.

• Data from before you had an account stays only in your browser until you clear it.
• Operational logs are kept for a short period for security and reliability, then deleted or aggregated.

Exact retention periods are still being finalized and are subject to legal review. The Privacy Policy is where they will be published.

The backup covers every sport — profiles, sessions, badges, saved video analyses and summaries of your Motion Lab swings (score, shot type and key focus). It is a data file, not a video archive, so keep your original clips in your camera roll if you want them.

Restoring shows a preview first and lets you either merge the backup with what is already there or replace it.

The box is offered only to a signed-in adult filming themselves, with the app set to English, never for an athlete marked as under 18, and ticking it changes nothing about your own analysis. If you tick it, we keep that video until you withdraw or 3 years after your last shared upload, whichever comes first. You can withdraw in My Data, which deletes every video you shared, and deleting your account deletes them too. A model already trained on a video keeps what it learned until it is next retrained, at least every 6 months. See the training-video privacy and retention schedule.

SwingVantage does use privacy-safe evidence to make the product more reliable — for example, each analysis sends an anonymous reliability record with no video or body positions, and when the "Sync your swing analyses" switch is on, a short summary of how well each read held up goes with your account copy. A separate switch in Settings, also called "Help improve SwingVantage", controls whether anonymized, aggregated insights from your use contribute, and you can turn it off. See what leaves your device.

If you start the optional AI second opinion, its sampled frames are processed by a third-party AI provider under that provider’s own privacy terms. See third-party services.

Your data is used to run the features you use, show your progress, keep the service reliable and secure, and send important product or account updates. Children’s data is never sold and is not knowingly used for advertising.

Some screens show promotions for SwingVantage’s own features. No outside ad network runs on SwingVantage today.

The service providers that help run SwingVantage process data on its behalf; they are listed on the subprocessors page.

Elsewhere, analytics that set cookies are on by default and you can switch them off; depending on what is enabled, they can include usage heatmaps and session replay. Change your choice at any time with Cookie settings in the footer of SwingVantage’s public pages.

Analytics that set no cookies also count page views and measure page speed, whatever your cookie choice. If your browser sends Do Not Track or Global Privacy Control, the analytics that set cookies stay off in every region, even if you accept them: traffic analytics and session replay do not load, and product analytics records nothing.

Separately from analytics, each Motion Lab analysis sends an anonymous reliability record whatever your cookie choice. It sets no cookie and carries no video, body positions or account ID — see what leaves your device.

The full detail is in the Cookie Policy.

• Hosting and delivery — runs the site for everyone.
• Account database and sign-in — stores your account, profile and practice data when you have an account, any video you choose to share for training, and the anonymous reliability records every analysis sends.
• Email — account messages such as sign-in emails and retest reminders.
• Analytics — usage measurement. Tools that set cookies follow your cookie choice; cookie-free page-view and page-speed counts do not.
• AI providers — only for optional AI features. AI Coach receives your question with the profile details, recent results and current One Fix it answers from. The AI second opinion receives a small sample of still frames. Photo import receives the photo you choose. Launch-monitor CSV import can send column names and a few sample rows for help mapping them. Your full video, email and account identifiers are not sent to AI providers.
• Abuse protection — your IP address and request counts, briefly, to rate-limit traffic.
• Payment processing — listed for when paid plans launch; nothing is charged today.

The subprocessors page names each provider, the data involved, and whether it is active or used only when configured.
