Privacy policy
Effective 19 October 2026 · The English version is the binding one; the Vietnamese one is a translation.
Contents
In short: Arista has no ads, no analytics and no trackers, and never asks for your name, email or password. Your photos, pages, collections and palettes stay on your iPhone. A picture leaves your phone only when you make a page in an AI style, and only after you have allowed it: it goes to Arista's server and on to OpenAI, which draws the page, and Arista keeps it at most two days. To count credits, Arista gives your phone an anonymous account, which you can delete in the app under Profile → Delete account.
1. Who is responsible
Arista (on the App Store as Arista Studio) is made by Ioniclabs, the developer named on its App Store page, which is responsible for the data described here. Privacy contact: ioniclabs.support@gmail.com.
This policy covers the Arista iPhone app and this website.
2. What stays on your phone
Photos you take or import, the pages you color, your artworks, collections, palettes, focus settings and your profile (the name and color you choose) are stored in the app on your iPhone. They are included in your iCloud or computer backup if you use one, and are deleted when you delete the app. Pages in the Original style are traced entirely on your iPhone; nothing is sent for them.
3. Your anonymous account
The first time you open Arista, it creates an anonymous account on its server so that credits and purchases can be counted. You never sign in. The account's key is kept in your iPhone's keychain, so the account survives deleting and reinstalling the app on the same phone.
| Data on Arista's server | Why | How long |
|---|---|---|
| A random account ID | To know whose credits are whose | Until you delete the account |
| Your credit balance and a ledger of each grant and spend: which AI page used credits, its style, and when | To give you the right credits, refund failed ones and handle disputes | Until you delete the account |
| The App Store transactions of your subscription (Apple's signed transaction: product, dates, transaction IDs, a renewal status; never your payment details or Apple Account) | To give your plan's credits once, renew them, and take them back if Apple refunds a purchase | Kept for accounting and to prevent abuse; on account deletion they are kept without your account ID |
| An identifier of your App Store account for this app (Apple's appTransactionId) | So the 30 free credits are given once per App Store account, not once per install | Kept without your account ID after deletion, for the same reason |
4. AI pages
AI pages are made only after you allow it on the permission screen; you can withdraw that at any time in Profile → Use photos with AI, and the rest of the app, including Original pages, keeps working without it.
- AI page: the photo, resized to at most 1536 pixels, is sent over an encrypted connection to Arista's server, which asks OpenAI to draw the coloring page.
- Kept at most two days. Arista's server keeps the photo and the finished page in private storage so that a page you paid for is never lost if the connection drops, and deletes them as soon as the app has them, or after two days at the latest.
- The AI services process pictures under their API terms. OpenAI does not use API data to train its models and may keep it for up to 30 days to detect abuse. Arista never uses your pictures to train AI.
- Pictures may be checked by OpenAI's safety filters; a picture it refuses is not charged.
- Reporting a page. If an AI page comes out offensive or wrong, open it and choose Share → Report this page. It opens an email to us with the page attached; you choose whether to send it. We read every report and answer within 48 hours, and use what you send only to handle the report and improve the styles' safety, then delete it.
5. Permissions
| Permission | When it is asked | How it is used |
|---|---|---|
| Camera | When you take a photo in the app | Only to take the photo you want to turn into a page |
| Add to Photos | When you first save a page | Only to add your artwork to your library; Arista can't read your library. Photos you pick are chosen in Apple's picker, which gives the app only those photos |
| Notifications | When you first start a focus session | A notification made on your iPhone when the session ends; nothing goes to a push service |
6. Purchases
Subscriptions are sold only through Apple's In-App Purchase. Apple takes the payment; Arista never receives your payment details or your Apple Account. The app sends Arista's server the signed transaction Apple gives it, and Apple notifies the server of renewals and refunds, so your credits stay right. Manage or cancel subscriptions in Settings › Apple Account › Subscriptions; refunds are Apple's to give, at reportaproblem.apple.com.
7. Who processes data, and where
We never sell personal data and share it only with the services Arista needs to run:
- Supabase (database, storage and server functions), in Singapore;
- OpenAI, USA: drawing AI pages;
- Apple: the App Store, purchases and their notifications;
- GitHub (GitHub Pages, USA) hosts this website.
Data may therefore be processed outside your country, including in Singapore and the USA. We rely on these providers' contractual safeguards for such transfers, and follow the procedures that apply to an organisation of our size, including under Vietnam's Personal Data Protection Law (No. 91/2025/QH15).
8. Your rights and deleting your data
- In the app: Profile → Delete account deletes your account on Arista's server: your credits and ledger, and any stored pictures and pages. App Store transaction records are kept without your account ID, for accounting and to prevent abuse. A subscription is billed by Apple and keeps renewing until you cancel it; the app reminds you and opens Manage subscription.
- On your phone: delete artworks and collections in the app, or delete the app to remove everything stored in it.
- Anything else: you may ask to access, correct or delete your data, withdraw consent, or object to processing, under the GDPR, the UK GDPR, the CCPA, Vietnam's PDPL or other laws that apply to you. Write to ioniclabs.support@gmail.com with your account ID (shown in Profile); we reply within 15 days. You may also complain to your data protection authority.
9. Security
Everything between the app and the server travels over encrypted connections. Each account can only reach its own data; pictures are kept in private storage reached only through short-lived links. Purchases are accepted only with Apple's signature, checked on the server. Only the developer can reach the server's data.
10. This website
The site sets no cookies and runs no analytics. It loads two typefaces from Google Fonts, so your browser fetches them from Google. Our host, GitHub, may keep technical logs such as IP addresses to run and secure the service, under its own policy.
11. Children
Arista is not directed at children under 13, and we do not knowingly collect personal information from them. It has no chat, no social features and no content visible to other people. Purchases need the permission of the Apple Account holder, and Apple's Ask to Buy works as usual.
12. Changes
We publish new versions here with a new effective date, and in the app. If we want to use data for a new purpose, we will ask for your consent first.
