Privacy Policy
The short version: the Dutie app does not collect your personal data. There are no accounts, no ads and no third-party analytics. We only receive your email address and the contents of your message when you choose to write to us (see section 5).
This policy explains what data Dutie (the iOS and Android apps, this website, dt.artsafari.io, and the support emails you send us) handles, why, and what you can do about it. We have tried to write it in plain language. “We” means the people who run Dutie.
1. What the app does not collect
- No accounts. The app never asks for your name, email address, phone number or any other sign-up details.
- No ads.
- No third-party analytics or tracking tools.
- We do not store your device identifiers.
2. Data that stays on your phone
Which copybooks you have read, your garden (the stones that settle when you finish a copybook) and your settings live only on your phone. They are never sent to our servers and we cannot see them. When you delete the app, they disappear with it.
3. Data our server keeps
When you buy a paid copybook, the app sends the transaction ID given by the store to our server, and the server checks the transaction with the App Store or Google Play. The only things the server keeps are:
- which store the purchase was made in (Apple or Google);
- the transaction ID given by the store;
- which copybook was bought;
- whether the transaction has been refunded;
- when it was last checked with the store.
This data is generated by the store and cannot be linked to your real identity: within this purchase data we have no name or email address for you, and no device identifier. We keep it to confirm that a purchase is valid, to let you download the copybooks you bought, and to stop providing a copybook after a refund.
4. Payment
Payments are handled by the App Store or Google Play. Your card and other payment details never pass through us.
5. When you write to us
When you write to us as described on the Support page, we receive the information you choose to give us:
- your email address and the display name on the message;
- the contents of the message;
- anything you attach, such as your phone model and system version, the version of Dutie, screenshots, and the order number from the store receipt.
We use this only to reply to you and to investigate the problem. The messages are sent and stored by the email service we use, and kept only as long as needed to deal with your question. You can write to us at any time to ask us to delete the messages and attachments you sent.
Please do not put passwords or card details in your email.
6. Website and server access logs
The servers behind this website and the app are provided by Cloudflare. Ordinary network access logs (for example IP address, time and requested URL) are handled by Cloudflare under its own privacy policy. We do not use these logs to identify or track individual users.
This website is made of plain static pages. It loads no third-party scripts, uses no analytics, and does not set cookies itself.
7. Third parties
Using Dutie involves the following third parties, each with its own privacy policy:
- Apple (App Store): Privacy Policy
- Google (Google Play): Privacy Policy
- Cloudflare (servers): Privacy Policy
- The email service we use: it handles the messages you send us.
8. Children
The Dutie app does not collect personal data from anyone, including children. If a child writes to us, section 5 applies to that message.
9. Keeping and deleting data
To clear the data on your phone, delete the app. The transaction records on our server cannot be linked to a real identity, so we cannot look up which record is yours. You can ask us to delete the messages and attachments you sent us. If you have questions about this data, please write to us.
10. Changes to this policy
When we change this policy we will update the “Last updated” date in the footer. Major changes will be explained clearly on this page.
