Privacy Policy
Last updated August 3, 2026
This Privacy Policy explains what information Coast Creative Studio (“Coast Creative,” “we,” “us”) collects, how we use it, and the choices you have. It covers our website at coastcreative.studio and every app we publish — the macOS suite (MOTHER, FATHER, BISHOP, and ASH), our widget apps (Lumen, Panel, NULL, and ROOK), Duesday, and TREKR for iOS.
The short version: we collect very little, we don’t sell your data, and our apps keep your information on your own device.
01
Information we collect
We keep this to what we actually need:
- When you contact us: your name, email, an optional phone number, and whatever you include in your message, sent through our contact form.
- When you buy an app: your purchase goes through our Shopify store. Shopify processes your payment and collects your billing details on its secure checkout, then delivers your download by email. We receive the order information we need — such as your name, email, country, and what you bought — to provide support and meet our tax and accounting obligations. We never see your full card number.
- When you download an app: we keep an anonymous count of total downloads per app. It’s a tally only and isn’t tied to you.
- Automatically: like most websites, our host (Vercel) records basic technical logs — such as IP address, browser type, and pages requested — to keep the site secure and running.
02
What our apps do NOT collect
This is the important part. Our apps run entirely on your Mac.
The API keys, tokens, passwords, settings, and site data you enter stay in local storage on your own computer. The apps connect directly from your Mac to the third-party services you choose — such as Vercel, Google, Microsoft Bing, GitHub, and Anthropic. That information flows between you and those services; it does not pass through Coast Creative, and we never receive or store it.
Any encrypted backup you create stays on your machine, or wherever you choose to save it, protected by a password only you know.
03
Duesday and your subscription data
Duesday keeps a record of what you pay for, so it’s worth being exact about where that information goes: nowhere.
Everything you enter — subscription and service names, prices, billing cycles, renewal and trial dates, categories, and any notes — is stored in a database on your own Mac. There is no account to create, nothing syncs to a server, and we never receive any of it.
Duesday makes one kind of network request, and it only goes one way. Every few days the app downloads its own catalog — a public list of well-known services and their typical prices — so the options you pick from, and the prices attached to them, stay current. That request is identical for every copy of the app and carries nothing about you or what you track. The file is hosted on GitHub, which, like any web server, can see the IP address asking for it.
Nothing travels in the other direction. Your subscriptions are never uploaded, and there is no Coast Creative server holding them. Renewal and trial reminders are scheduled and shown by macOS on your own machine, and a cancellation link opens in your normal browser only when you choose to click it.
The only files Duesday can read or write are the ones you choose yourself. That is how the CSV and JSON exports work — they are saved where you point them, and we never get a copy.
04
How we use information
We use the little we collect to:
- Respond to your inquiries and provide the services you ask for.
- Deliver app purchases and provide support.
- Keep the website secure and working.
- Understand overall interest through aggregate download counts.
- Meet legal, tax, and accounting obligations.
05
We don’t sell your data
We don’t sell your personal information, and we don’t share it with advertisers. We keep tracking to a minimum and don’t use advertising cookies.
06
Service providers we rely on
A few trusted providers help us run the business, and each has its own privacy policy:
- Vercel — website hosting.
- Resend — delivers the emails sent from our contact form.
- Shopify — powers our online store, processes app purchases, and delivers your download after checkout.
- For the apps, the third-party services you connect (Google, GitHub, Vercel, Microsoft Bing, Anthropic, and similar) handle your data under their own policies.
07
Data retention
We keep contact messages and order records only as long as we need them for the purpose we collected them and for legal or accounting requirements, then delete or anonymize them.
08
Your rights
Depending on where you live — for example under the California Consumer Privacy Act (CCPA/CPRA) or the EU/UK GDPR — you may have the right to access, correct, delete, or receive a copy of your personal information, and to opt out of its sale. We don’t sell personal information. To exercise any of these rights, just email us and we’ll take care of it.
09
Security
We use reasonable safeguards to protect the information we hold. The local-first design of our apps means the most sensitive data — your keys and tokens — never leaves your device in the first place.
10
Children
Our website and apps aren’t directed to children under 13, and we don’t knowingly collect information from them.
11
Where your information is processed
We’re based in the United States. If you contact us or buy from us from another country, your information will be processed in the U.S. and other countries where our providers operate.
12
Changes to this policy
We’ll post any updates here and change the “last updated” date above.
