  1. Cookie and Local Storage Policy

Last updated: [DATE]

4.1 Summary

DESHANK does not use advertising, tracking or analytics cookies. We only use cookies and storage that are strictly necessary to provide the features you ask for. These include keeping you signed in to your account and making secure payments. Under the Privacy and Electronic Communications Regulations 2003 (PECR), strictly necessary storage does not require consent, but we want you to know what it is.

4.2 What we store on your device

Name / type Purpose Duration Strictly necessary?
Local storage / IndexedDB: player profiles and swing history Saves the profiles and history you create so you can see your progress Until you delete it (Delete player / Clear history) or clear site data Yes – a feature you request
Local storage: settings (e.g. chosen voice, preferences) Remembers your choices Until you delete it or clear site data Yes
Service worker and cache storage Lets the app load quickly and work offline after first load Until updated by the app or you clear site data Yes
Sign-in / session cookie or token [NAME – DEVELOPER TO CONFIRM] Keeps you signed in and protects your account [Session / X days] Yes
Stripe cookies on checkout and billing pages (for example the fraud-prevention cookies __stripe_mid and __stripe_sid where Stripe code runs on our pages) [DEVELOPER TO CONFIRM NAMES] Processes payments securely and prevents fraud [e.g. __stripe_sid 30 minutes; __stripe_mid 1 year – CONFIRM] Yes – for a payment you ask for
[Any security or hosting cookie set by HOST, e.g. load-balancing – NONE EXPECTED] [Purpose] [Duration] [Yes/No – DEVELOPER TO CONFIRM]

The developer has confirmed that in production no third-party scripts, fonts, analytics or embedded content are loaded, other than Stripe's code on checkout and billing pages. Where you are sent to Stripe-hosted checkout or billing pages, those pages are on Stripe's own website and Stripe's privacy and cookie policies apply (stripe.com/gb/privacy). [DEVELOPER: run a final browser cookie and storage check on deshank.com after deployment (and confirm the deshank.co.uk redirect sets no cookies), and confirm whether the host sets any cookie.]

The speech service your browser uses for voice commands is part of your browser, not our website. It does not set cookies on our site. See Privacy Policy section 3.5.

4.3 Managing storage

You can delete DESHANK data with the in-app controls, or through your browser settings (for example “Site settings” or “Clear browsing data”). Deleting it will remove your profiles and history permanently and sign you out. It does not cancel your subscription.

4.4 If we add analytics or other non-essential cookies

We will update this policy first. Where consent is required by law, we will ask for it with a banner that makes it as easy to reject as to accept, and non-essential cookies will not be set until you choose. [SOLICITOR NOTE: the Data (Use and Access) Act 2025 introduces some PECR exemptions for certain low-risk analytics, subject to clear information and a simple way to object. Review against the in-force rules and ICO guidance before adding analytics.]

4.5 Banner text

Option A – for now (no non-essential cookies). A short notice, not a consent request:

No tracking here. DESHANK only uses what’s needed to make the app work – such as keeping you signed in, secure payments, and saving your players, swing history and offline files on your device. No advertising or analytics cookies. [Learn more] [OK]

Option B – only if non-essential cookies are introduced later:

Your choice on cookies. We use essential storage to make DESHANK work. With your permission, we’d also like to use [analytics] cookies to understand how the app is used and improve it. These are off unless you turn them on. [Accept all] [Reject all] [Manage settings] [Cookie Policy]
