Privacy Policy
GoodSwing · Effective [date] · Version 1.0
Jinjo Labs Ltd. ("we") runs GoodSwing, an app that analyzes your golf swing videos. This policy explains what we collect, why, where it is stored, who processes it for us, how long we keep it, and your rights. It applies to everyone who uses the app, including guest accounts.
Summary
- Your videos and results are stored and processed in the United States, on Amazon Web Services (AWS).
- We use your data only to run the service for you. We don't sell it, don't use it for advertising, and nobody else in the app can see it.
- To write coaching text, we send your swing numbers (not your video, not who you are) to an AI service provider.
- Original videos are deleted after 30 days. You can delete any swing or your whole account in the app at any time.
1. What we collect
| Category | What | When |
|---|---|---|
| Account | An account ID we generate; your sign-in method (guest, Apple or Google) and that provider's user ID; your email address if Apple or Google shares it (Apple may give a private relay address) | When you start your first analysis (guest) or sign in |
| Settings | Dominant hand, language, time zone, notification settings, the version and time of the terms and policy you accepted | When you set them |
| Swing videos | The video file you upload, including any sound it recorded, and its recording time. The app removes location and other embedded metadata before upload | When you upload a swing |
| Analysis results | Body keypoint positions over time computed from the video, swing metrics, scores, detected faults, coaching text, club and camera angle you chose, session grouping and progress | When we analyze a swing |
| Subscription | Your plan, its status and renewal or end date, and the store's purchase records for it. Apple or Google handles the payment; we never see your payment details | When you subscribe, renew, redeem a code or restore purchases |
| Notifications | Push token for your device | Only if you turn notifications on |
| Technical logs | IP address, time and type of requests, app version and operating system, error details | When the app talks to our servers |
We don't ask Apple or Google for your name, and we don't collect your location, contacts or photos other than the videos you choose. We don't use videos or pose data to identify anyone (no face recognition).
Body and head points. To measure your swing, our model finds points on your body in each frame of the video, including your head (eyes, ears and nose). Some laws treat points on the face as biometric data, so we follow these rules for them:
- We use them only to measure your swing and draw the pose overlay, never to identify you.
- Of the head points we keep only one, the center of your head; the others are discarded during the analysis.
- We never sell, lease or trade them, and we don't share them with anyone. The AI service that writes coaching gets only the measurements.
- We delete them when you delete the swing or your account.
- By tapping "Agree and upload" before your first upload, you consent to this.
Other people in your videos. Only upload videos of yourself, or of other people who agreed to it.
2. Why we use it
- To analyze your swings, write coaching, and show your history and progress.
- To create and keep your account (including guest accounts and linking them to Apple or Google).
- To count your free analyses and check your subscription.
- To send notifications you turned on (for example, when an analysis is ready).
- To keep the service working and secure: troubleshooting, preventing abuse, and measuring reliability and cost.
- To answer your questions and meet legal obligations.
We don't use your data for advertising, don't sell it, and don't use it for any other purpose (including training models) without asking you separately first.
3. How long we keep it
| Data | Kept until |
|---|---|
| Original uploaded video | 30 days after upload |
| Playback video (720p), pose data, results, coaching | You delete the swing or your account |
| Account, settings and subscription status | You delete your account |
| Guest accounts with no activity | Deleted with all their data after 90 days without activity |
| Technical logs | 30 days |
| Backups | Removed from backups within 35 days of deletion |
When you delete a swing or your account, we delete it from our systems without undue delay, including videos, results, push tokens and your sign-in account (and we revoke Sign in with Apple access). If a law requires us to keep something longer, we keep only that, only for that period, separately from other data.
4. Sharing
We don't give your data to third parties for their own use. The exception is when the law requires it (for example, a valid court order), and then only what is required.
5. Service providers and transfer outside your country
We use these companies to run the service. They process data only on our instructions and under contract, receive it over encrypted connections when their task needs it, and keep it only as long as that task requires (for AWS, our retention periods in section 3).
| Provider (contact) | Country | What they receive | Why |
|---|---|---|---|
| Amazon Web Services, Inc. (aws.amazon.com/privacy) | US | All service data | Hosting, storage and processing |
| Google LLC, Firebase Authentication (firebase.google.com/support/privacy) | US | Account and sign-in data | Sign-in and guest accounts |
| Upstage Co., Ltd. (infosec@upstage.ai) | Korea, US | Swing analysis results only: no video, nothing that identifies you | Writing coaching text |
| RevenueCat, Inc. (compliance@revenuecat.com) | US | Account ID and subscription purchase records: no swing data | Managing subscriptions |
| Apple Inc. and Google LLC push services (apple.com/legal/privacy/contact, policies.google.com/privacy) | US | Push token and notification text | Delivering notifications, if you turn them on |
So if you use the app from outside these countries, your data is transferred to and stored in them. If we change a provider, we update this section.
If you don't want this transfer. The service runs on these providers, so it can't be used without it. You can stop at any time by deleting your account. Notifications are optional and can be turned off in Settings.
Laws abroad. Data stored in another country is subject to that country's laws, and its courts, law enforcement and national security authorities may access it under those laws.
6. Your rights
You can:
- see and correct your data (most of it is in the app);
- delete any swing, or your whole account and all its data, in the app (Settings);
- ask for a copy of your data, ask us to stop processing it, or withdraw consent, by contacting us (section 10).
We respond within 10 days of receiving your request. If a good reason makes us need longer, we tell you why and when to expect our answer. A legal representative can act for you. Guests have the same rights.
7. Security
- Encryption in transit (TLS) and at rest.
- Videos and results are private: only your signed-in app can reach them, through links that expire quickly. Every request is checked against your account.
- Our staff and systems get only the access they need, and access is logged.
8. Automated analysis
Scores, faults and coaching are produced automatically from your video. They are practice feedback only and have no legal or similarly significant effect on you. They are not medical advice.
9. Children
The app is for adults and is not for anyone under 18. We don't knowingly collect data from people under 18. If you think someone under 18 is using the app, contact us and we will delete the account.

11. Changes to this policy
We post every change in the app. Changes that don't reduce your rights take effect when posted; changes that reduce your rights take effect at least 7 days after we announce them. Where the law requires your consent, we ask for it again before your next upload. Earlier versions are available on request.
