Legal Privacy
Privacy Policy for Tatscale
Tatscale (“the app”, “we”, “us”) is made and run by Henrik Arnrød (also written Henrik Arnroed, the name on the App Store), an independent developer based in the United States. He decides how your personal information is used and is responsible for it (the “controller” under the EU and UK General Data Protection Regulation, GDPR). You can reach him at hello@tatscale.com.
This policy explains what information the app collects, how it is used, and your choices. We keep this deliberately short and plain.
Summary
- You can use the app as a guest without giving us any personal data.
- If you sign in, we store your email address, your name if you share it, an account ID, and a count of how many exports you have used.
- You sign in with Sign in with Apple or a one-time code sent to your email.
- If you subscribe, Apple tells us about events such as renewals and offer codes used, but never your payment details. If you subscribe to Artist, we link that subscription to your account so we can give you your AI renders.
- We do not sell your data, show third-party ads, use analytics or tracking tools, or track you across other apps or websites.
- Your stencils, designs, and print settings stay on your device. The one exception is AI Stencil: when you use it, the photo you choose is sent to Google’s Gemini API to draw the stencil. We don’t keep that photo.
- If you leave your email on one of our website sign-up pages, we store it only to send you what you asked for.
What we collect
Account information. If you sign in, we store:
- Your email address — either one you type in, or the email provided by Sign in with Apple. If you use Sign in with Apple and choose “Hide My Email,” we only receive Apple’s private relay address.
- Your name, if you share it (for example through Sign in with Apple).
- A unique account identifier used to recognise you across sessions and devices.
Export count. We store the number of exports you have used, so the free trial works across reinstalls and devices. We store only the number, never the files you export.
Sign in with Apple token. If you sign in with Apple, we store a token issued by Apple. It is used only to disconnect Tatscale from your Apple Account when you delete your account.
You can use the app as a guest without providing any of this. Guests can design freely but need to sign in to export or print.
Purchase information. If you subscribe, the transaction is handled entirely by Apple. We do not see or store your payment details, and your subscription status is checked with Apple on your device.
Apple also notifies our server when something happens to a subscription — for example when it starts, renews or ends, or when an offer code is redeemed. Each notice includes details such as the plan, any offer code used, the dates, the price and currency, the App Store country, whether it will renew, and Apple’s transaction reference. It does not include your name, email address or payment details. We do not link Pro subscription records to your Tatscale account; Artist subscriptions are linked, as described below. We keep these records to see which offer codes, such as those shared by partner tattoo artists, lead to subscriptions.
Website sign-ups. If you enter your email on a sign-up page on tatscale.com (for example to receive an offer link or to join the Artist tier waiting list), we store that email address, which page you used, and when. We use it only to send you what that page promised, and we don’t link it to a Tatscale account.
AI Stencil. If you use AI Stencil, the photo you choose is sent to our server and passed on to Google’s Gemini API, which draws the stencil and sends it back. You tick a box agreeing to this before your first render, and no photo is sent without it.
We do not store your photo. It is held in memory only long enough to pass it on, and it is never written to our database or file storage. Under Google’s terms for paid services, Google doesn’t use your photos or stencils to improve its products. Google keeps them for a limited time, only to detect misuse of its service and to meet legal requirements, and they may be processed in any country where Google operates.
Please only use photos you have the right to use, and avoid photos of children or of anyone who hasn’t agreed.
Everything else happens on your iPad: sharpening the stencil to print resolution, converting it to vector, and making the colour palette and high-contrast versions. Results stay on your iPad, in Recent stencils for 7 days, and on any canvas you add them to for as long as you keep that canvas.
For each render we keep a record of the date, whether it worked, and the subject, style and shape you chose. It never includes the photo or the stencil. We use these records to count your monthly renders and to track what the service costs us.
We also keep a record of your agreement to AI processing: the wording you agreed to, when, and your app version.
Artist subscriptions and renders. If you subscribe to Artist, we store your plan, when it expires and Apple’s reference for your subscription, linked to your account. If you buy extra renders, we store how many you have left and a record of each purchase.
Your designs stay local. Imported images, stencils, guides, grids, and print/export settings are stored on your device only. We do not view or store your artwork. The only time anything leaves your iPad is when you send a photo to AI Stencil, as described above.
How we use your information
- To provide account login and keep you signed in.
- To run the free trial by counting your exports.
- To see which offer codes lead to subscriptions and renewals, for example codes shared by partner tattoo artists.
- To email you the offer link or launch news you signed up for on our website.
- To create the stencils you ask for with AI Stencil.
- To count your monthly renders, check your Artist subscription, and track what the service costs.
- If you subscribe to Pro or Artist, to occasionally email you news about Tatscale, such as new features. Every one of these emails has an unsubscribe link. We don’t send them to free accounts, which only get sign-in codes, unless you sign up for news on our website.
Our legal reasons for using your information
The GDPR asks us to name the legal reason for each use. Ours are:
- To provide the service you asked for (performing our contract with you): your account and sign-in, the export count behind the free trial, AI Stencil, and your Artist subscription and render allowance. The box you tick before your first AI render makes sure you know your photo will leave your iPad before it does.
- Our legitimate interests, which we’ve weighed against your privacy: measuring which offer codes lead to subscriptions, tracking what the service costs, keeping the service secure and preventing misuse, keeping a record of what you agreed to before using AI Stencil, and emailing subscribers news about Tatscale. You can object to any of these at any time (see “Your rights” below), and you can always unsubscribe from emails.
- Your consent: when you leave your email on a website sign-up page. You can withdraw it at any time by emailing us or using the unsubscribe link.
- Legal obligations: keeping anonymous render and purchase records for accounting and tax.
Who we share it with
We use the following service providers to operate the app:
- Apple — for Sign in with Apple, subscription billing, and notices about subscription events.
- Google — to process the photo you send to AI Stencil and return the stencil.
- Supabase — to securely store your account information, export count, subscription and render records, and website sign-ups. It stores this data in the United States.
- Resend — to deliver the one-time sign-in codes we email you, and the emails you sign up for on our website. It is based in the United States.
- Cloudflare — to host and protect tatscale.com and to forward email sent to hello@tatscale.com.
These providers process data on our behalf, under data processing agreements that limit what they can do with it. We do not sell your personal information to anyone.
Transfers outside Europe
Tatscale is run from the United States, and our providers store and process data in the United States and, for Google and Cloudflare, possibly other countries. When your information leaves the European Economic Area, the UK or Switzerland, we rely on the provider’s certification under the EU–US Data Privacy Framework (and its UK and Swiss extensions) where it has one, and otherwise on the European Commission’s Standard Contractual Clauses in our agreement with that provider. You can ask us for a copy of the relevant safeguards.
Our website
tatscale.com uses no analytics, no advertising and no tracking cookies, and its fonts are served from our own site. Like any website host, Cloudflare processes your IP address to deliver the pages and protect them from attacks, and may set a strictly necessary security cookie for that purpose.
Data retention and deletion
We keep your account information for as long as your account exists.
You can delete your account at any time in the app: open the menu (top left), go to your account pane, and tap Delete account. This permanently deletes your email, name, account ID, export count, AI agreement, Artist subscription link and any unused bought renders, and disconnects Sign in with Apple. You can also request deletion by emailing us (see below).
We keep render records and records of bought renders after an account is deleted, with the link to you removed. They contain no name, email, photo or stencil, and we use them for accounting.
Deleting your account does not cancel an active subscription. Subscriptions are managed by Apple in Settings.
We keep a website sign-up until we have sent what you asked for and it is no longer needed. Email us to have it removed at any time.
Pro subscription records are not linked to your account, so deleting your account does not remove them. We keep subscription records for 5 years to measure how offer codes perform over several renewals, and then delete them.
Your choices
- Use as a guest — provide no personal data at all.
- Don’t use AI Stencil — nothing leaves your iPad for it unless you use it.
- Unsubscribe from news emails at any time, with the link in every email.
- Delete your account in the app, or request deletion by emailing us.
Your rights
Wherever you live, you can ask us to:
- Access the personal information we hold about you and get a copy of it.
- Correct information that is wrong.
- Delete your information (you can also delete your account yourself in the app).
- Move your information: receive it in a common, machine-readable format.
- Restrict how we use it, or object to uses that rely on our legitimate interests.
- Withdraw consent you gave us, at any time, without affecting what we did before.
Email hello@tatscale.com from the address on your account, or tell us which account it is. We’ll reply within one month. We don’t charge for this.
If you live in the EU, the EEA or the UK and you’re unhappy with how we’ve handled your information, you can complain to your local data protection authority, for example Datatilsynet in Denmark or the ICO in the UK. We’d appreciate the chance to sort it out with you first.
We don’t use your information for automated decisions that have legal or similarly significant effects on you.
Children
Tatscale is not directed at children under 13, and we do not knowingly collect personal information from them.
Changes to this policy
We may update this policy from time to time. The “Last updated” date at the top reflects the latest version. If we make a change that matters, such as using your information in a new way, we’ll tell you in the app or by email before it takes effect.
