Read how we handle your data.
Last updated 10 November 2026. Doved Studio makes Scratchmaxx and runs scratchmaxx.com. This policy covers Scratchmaxx on Android and iPhone, and this website.
Who we are
We are Doved Studio. We build and run Scratchmaxx, the golf swing and round app (Android package com.dovedstudio.titangrips.golf), and this website. Write to [email protected] with any privacy question or request.
What you give us
- Profile: your nickname, height, handedness, level, goals and settings. Your height scales the inches you read on your swing.
- Swing clips: the golf swings you record or import, the frames we cut from them, and the body measurements taken from them (head, hips and forward bend at address, the top, impact and the finish).
- Rounds and courses: your scorecards (strokes, putts, fairways, greens, bunkers), the shots and clubs you mark, the courses you add with their pars, stroke indexes, course rating and slope, and the green positions you save.
- Location: when you place a green, mark a shot or check the distance to a green, you share your phone's location. To find the mapped greens near you, we send that location to our server and look them up in OpenStreetMap.
- Questions: the messages you send the in-app coach about your swing, your clubs or your rounds.
- Purchases: product identifiers, entitlement status and subscription events. You pay through Google Play or the App Store; we never see your card number.
- Device and usage: app version, device model and operating system, crash diagnostics, the screens you open and the features you use, tied to a random identifier.
How your swing read works
The head, hip and forward bend numbers come from your phone: the body reading runs on the device. To read the rest of your swing (setup, turn, path, hands, tempo and finish), we send the clip's frames, your measurements and your profile context through our servers on Cloudflare to an external AI provider, then show you the result. Before we send anything to an AI provider for the first time, you see a permission screen that names the providers and the data. Choose Not Now and you keep every feature that needs no external provider.
Who helps us run Scratchmaxx
- Anthropic (Claude), Google (Gemini and Vertex AI), Alibaba Cloud (Qwen): swing frames, your measurements, profile context and the prompts that produce your swing read. One read may reach more than one of them when we switch providers after a failure.
- DeepSeek: the questions you ask the coach, with the swing and round context each answer needs.
- Cloudflare: our servers, databases and the storage for your clips.
- OpenStreetMap, through the Overpass API: the location we send to find mapped greens near you.
- Google Play and Apple: app distribution, purchases and subscription billing.
- RevenueCat: subscriptions and entitlements.
- PostHog: product analytics on screens and features, tied to a random identifier.
- AppsFlyer, Meta and TikTok: advertising measurement, only in builds that include their tools and only after you give any permission your phone asks for.
We never sell your personal information. We share it only with providers whose terms require them to protect it at least as well as this policy does.
Why we use it
- To give you your swing read, your fix, your drills, your card, your carries, your handicap index and your stats.
- To save your records, restore your purchases and manage your subscription.
- To keep accounts safe, stop abuse and fix crashes.
- To learn which features help you and, with your permission, which ads brought you.
How long we keep it
Your rounds, courses and settings live on your phone. We keep the data on our servers while you use Scratchmaxx and as long as we need it to serve you, settle disputes, stop fraud, keep backups and meet legal duties. We use access controls and encryption in transit, and no system can promise perfect security.
Your choices
Decline AI data sharing, decline tracking, turn location or the camera off in your phone's settings, or stop using a feature at any time. Ask us for a copy of your data, a correction or a deletion by writing to [email protected]. When you delete Scratchmaxx from your phone, you remove what it stored there; write to us and we delete what our servers hold. We may ask you to confirm it is you first.
This website
We set no advertising cookies on scratchmaxx.com. When you join a launch list, you give us your email, the phone you picked, the page and the spot you signed up from, and your consent; we store them in Cloudflare D1 and send you the email you asked for. Cloudflare Turnstile checks you're human and processes your IP address for security. Our server keeps standard request logs (IP address, browser, page, time) for security and reliability. Write to [email protected] to leave the list or delete your signup.
Children
You need to be 13 or older to use Scratchmaxx, or the higher minimum age your country sets. If you think a child gave us personal data without valid permission, write to [email protected] and we delete it.
Where your data travels
Our providers may process your data outside your country, under different data protection laws.
Changes to this policy
When our features, providers or legal duties change, we update this page and its date. When a change affects your choices, we tell you in Scratchmaxx before it applies.
