This policy explains what TEKRISE ("we", "us", "our") collects when you use our
AI tennis swing-analysis app and website, how we use and share it, and the
choices you have. We try to collect as little as possible — for example, your
full recording never leaves your phone; only a short clip of the swing does.
01 Who Can Use TEKRISE (Age)
TEKRISE is for ages 13 and over.
You must be at least 13 years old to create an account or use the
app. If you are in the European Economic Area or the United Kingdom, you must be at
least 16 (or the minimum age of digital consent in your country, if
it is higher).
TEKRISE is a general-audience app and is not directed to children under 13.
We do not ask for your date of birth or age, and we do not knowingly
collect personal information from children under 13. If you believe a child under 13 has
provided us with personal information, please contact us and we will
delete the account and associated data.
A parent, guardian, or coach who is 13+ (16+ in the EEA/UK) may use their own account
to record and analyse a younger player's swing — but only with the consent described in
"Videos that include other people" below. The account, and
responsibility for it, belongs to the adult or eligible user, not the child.
02 What We Collect
Information you give us
- Account details — your email address and the name you provide at
sign-up, or the equivalent details from a Google, Apple, or Facebook sign-in if you use
one. Authentication is handled by our backend provider (Supabase); we do not store your
password ourselves.
- Player profile — your dominant hand, self-described playing level,
and gender (male, female, or "prefer not to say"). Gender is
optional — choosing "prefer not to say" is fine. We use these only to
tailor the coaching feedback, because typical swing mechanics can differ. We do not use
gender for advertising or share it for marketing.
- Your choices — your acceptance of our Terms, your notification
preference, your language, and whether you opt in to "Help improve TEKRISE".
Information created when you analyse a swing
- Swing video clip. When you record or upload a swing, the app saves
the full video on your device and uploads only a short clip — capped at
about 3 seconds — of the swing itself. The full original recording is
not uploaded; it stays on your phone.
- Movement & technique data. We process the clip to derive
body-position ("pose") data and biomechanical measurements such as joint angles and body
rotation. This describes how you move and is derived from your video.
- Analysis results. Your overall score, per-phase scores, the shot
type, and the written AI coaching feedback generated for each analysis.
Information collected automatically
- Usage & entitlement data — counts of analyses you run, which
coach you chose (Standard or Grand Slam), your subscription tier, and rewarded-ad
credits, used to enforce usage limits, run subscriptions/ads, and detect abuse.
- Basic technical data — such as the app version/build, needed to keep
the app working and to require updates when necessary.
03 How We Use It
- To record, analyse, and score your swing and generate AI coaching feedback.
- To personalise that feedback using your profile (dominant hand, level, and gender).
- To create and manage your account and keep you signed in.
- To run subscriptions, rewarded ads, and usage limits, and to prevent fraud and abuse.
- To maintain, secure, and improve the service, and to comply with legal obligations.
04 How We Share It
We do not sell your personal information. We share data only with the
service providers needed to operate the app, and only for the purposes below.
- AI coaching providers (Google and Groq). To generate your feedback,
we send the movement/technique data derived from your swing — along with the shot type,
dominant hand, playing level, and gender — to third-party AI services (currently Google
and Groq), which process it and return coaching text. This processing happens on their
systems and is subject to their terms.
- Hosting and storage (Supabase). Your account data, the uploaded swing
clip, your analysis results, and usage records are stored with our backend provider.
- Subscriptions (RevenueCat). If you purchase a subscription, purchase
and entitlement data is processed by RevenueCat and the relevant app store (Apple App
Store or Google Play) to manage it.
- Advertising (Google AdMob). If you watch a rewarded ad to unlock an
analysis, Google AdMob serves the ad and we verify the reward.
We may also share information to comply with the law, enforce our Terms, or protect the
rights and safety of our users and our service.
05 Videos That Include Other People
Filming someone else (including a child)?
If your swing clip shows anyone other than you — for example a hitting partner, or a
player you coach or are a parent of — you must have that person's permission to record and
upload them. If they are a minor, you confirm you are their parent or legal
guardian, or that you have the consent of their parent or guardian.
You are responsible for the content you upload. By uploading a clip you confirm you have the
right to do so and the consent of anyone appearing in it. If you need a video containing
another person removed, contact us.
06 Optional: Helping Us Improve
In your profile you can turn on "Help improve TEKRISE". When this is on, we
retain the derived biomechanical measurements from your analyses so we can improve our
analysis and coaching over time. This setting is off by default, and you
can turn it off at any time in your profile; turning it off stops future collection for this
purpose.
07 How Long We Keep It & Deletion
- Your swing clips, analysis results, and account data are kept while your account is
active.
- You can ask us to delete your account and associated data at any time by contacting us
(see Contact). When you do, we delete or de-identify your personal
data. For security and abuse-prevention, some audit records are retained with your identity
removed (de-identified) rather than deleted.
- The full original recordings never leave your device, so deleting those is done on your
phone.
08 Your Rights & Choices
- You can edit your profile and change your notification, language, and "Help improve
TEKRISE" preferences at any time.
- You can request access to, correction of, or deletion of your personal data and account
by contacting us.
- Depending on where you live, you may have additional rights (for example, under the GDPR
in the EEA/UK, or the CCPA/CPRA in California) such as access, deletion, portability, and
the right to object to or restrict certain processing. To exercise any of these, contact us
below.
09 Security
We use reasonable technical and organisational measures to protect your data, including
encryption in transit (HTTPS) to our backend and to the AI providers. No method of
transmission or storage is completely secure, so we cannot guarantee absolute security.
10 International Users
TEKRISE is operated from Australia, and our service providers may process and store data in
other countries. By using the app you understand your information may be transferred to and
processed in countries with different data-protection laws than your own. Where required, we
rely on appropriate safeguards for these transfers.
11 Changes to This Policy
We may update this policy from time to time. When we make a material change, we will update
the version and effective date above and, where appropriate, ask you to re-accept in the app
before you continue.
