Privacy Policy
Last updated: October 3, 2026
Artcoast LLC (“Artcoast,” “we,” “our,” or “us”) respects your privacy. This Privacy Policy explains how we handle information in connection with our mobile and desktop applications, website, and related services.
This Policy applies to applications published by Dmitry Mashkin and Artcoast LLC, including iOS, iPadOS, and macOS apps, as well as the website artcoastdesign.com.
1. Overview
We design our products to use as little personal data as possible.
Most of our apps do not require account creation or sign-in. We do not sell personal data. We do not use third-party advertising SDKs in our apps, and we do not use app data for ad targeting, retargeting, or cross-app profiling.
Some apps offer optional AI-powered features. When you choose to use those features, certain content you provide may be processed by third-party AI service providers in order to generate responses, summaries, insights, or suggestions.
Our website may process customer information when you make a purchase or contact us.
2. Mobile and Desktop Apps
2.1 General App Privacy
Most of our apps do not require registration, login, or account setup.
Depending on the app and the features you use, our apps may process:
text you enter into the app
entries and content stored locally on your device
optional exported files such as PDF or TXT
optional location data when needed for app functionality
optional Apple Health data, only if you explicitly grant permission
purchase and subscription status provided by Apple
In general, our apps are designed so that user content remains primarily on the device unless you choose to use a feature that requires transmission, such as AI processing, export, sync, or sharing.
2.2 AI Features
Some of our apps provide optional AI-powered features. When you actively use those features, relevant content may be sent to third-party AI service providers for processing.
We use our own backend to route AI requests. As part of normal operation, we do not use that backend to store the app content you submit for AI processing, except where described in the app-specific disclosures below (NOPE receipt scanning). Requests are forwarded to third-party AI service providers so the requested feature can work.
We do not sell AI-submitted content.
We do not use AI-submitted content for advertising.
We do not intentionally create marketing profiles based on AI-submitted content.
Because AI processing is provided by third parties, their own privacy, security, and retention practices may apply to the processing they perform.
2.3 App-Specific Disclosures
Lunadream
If you use AI features in Lunadream, the app may process dream descriptions and other text you choose to enter. That content may be sent to a third-party AI service provider in order to generate dream-related interpretations or responses.
Weather Assistant AI
If you use AI features in Weather Assistant AI, the app may process your location or location-based weather context, current weather information, and any text you submit. This information may be sent to a third-party AI service provider only to generate weather-related insights or advice.
NOPE: Spend Smart
Purchase check. If you use AI features, the app may send the item name, price, category, optional purpose and your answers to a third-party AI service provider (OpenAI) to generate spending feedback. Everyday purchases may be assessed on the device without AI.
Expense journal. Expenses you add (items, amounts, dates, categories, notes) are stored on your device and, if iCloud is enabled, synced through Apple to your private iCloud database so they appear on your other devices. We cannot access your iCloud data. Expenses are kept until you delete them; "Delete all expenses" removes them on all your devices.
Receipt scanning. Receipt photos are read on your device and are never uploaded. If you allow AI receipt scanning, only the recognized receipt text, with tax IDs, phone numbers, email addresses and street addresses removed on the device, is sent through our backend to OpenAI to split it into items and amounts. To enforce the monthly scan allowance and prevent abuse, our backend verifies your App Store subscription and Apple App Attest and stores: a pseudonymous subscription identifier (a keyed hash), monthly usage and cost counters, and the parsed result in encrypted form for up to 24 hours so an interrupted scan can be recovered without being counted twice. Scan records are deleted within about three months. Revoking receipt AI permission in Settings deletes cached results from our backend. We do not use receipt content for advertising or profiling.
Sugar AI (Blood Sugar Journal)
Sugar AI may process user-provided content such as glucose entries, insulin entries, food or nutrition entries, calories, notes, and journal text.
By default, these entries are stored locally on the device.
If you choose to use AI insight or AI reporting features, relevant portions of that data may be sent to a third-party AI service provider in order to generate summaries, reports, observations, or insights.
Sugar AI may also support PDF export and TXT export.
Sugar AI may also read from or write to Apple Health, but only if you explicitly grant permission. In the future, this may include data such as glucose, insulin, calories, and other nutrition-related data supported by the app.
Brushes / Brushes for Procreate
Brushes stores favorites, downloaded materials, saved inspiration, and app preferences locally on your device. Purchases and subscriptions are processed by Apple; we do not receive your payment card details.
Optional analytics and crash reporting
Starting with Brushes 5.0, the app offers separate choices for usage analytics and crash reporting. Both are disabled by default. You can use the app without enabling either service and change your choices in Settings. Earlier versions use Firebase Analytics and may request Apple’s tracking permission; the available privacy controls differ by version.
With your permission, we use Google Firebase Analytics to understand feature usage and improve the app. Data may include app installation identifiers, device and operating system information, app version, language, approximate location such as country or region derived from your IP address, interactions with materials and features, and purchase or subscription events. Brushes does not request GPS location for analytics.
With your permission, we use Google Firebase Crashlytics to diagnose technical problems. Reports may include installation identifiers, crash traces, device and operating system information, and technical details about errors.
We do not attach your artwork, search queries, font preview text, saved idea text, or Apple receipt contents to our custom analytics events or error reports.
Disabling analytics stops collection and resets local Analytics data. Disabling crash reporting stops new app-recorded error reports and requests deletion of unsent reports; changes to automatic crash reporting take effect on the next app launch. These settings do not delete information already received by Google.
Daily inspiration
Daily drawing ideas may be generated using a third-party AI service and delivered through our server. This feature requests shared content and does not send your artwork or personal text to the AI provider. Previously downloaded or built-in ideas remain available when the service cannot be reached.
Motion effects
Device motion is used locally to animate light effects on illustrations. Motion readings are not sent to our servers or analytics providers.
For privacy questions or requests concerning information we control, contact hello@artcoastdesign.com.
2.4 Health Data and Apple Health
Some apps, including Sugar AI, may access Apple Health data if you give permission through Apple’s authorization controls.
We only access Health data for the features you choose to enable. We do not access Apple Health data unless you explicitly authorize that access.
Depending on the feature, Apple Health-related data may include glucose, insulin, calories, food or nutrition-related information, and other categories supported by the app.
Health-related entries and imported information may remain stored locally on your device unless you choose a feature that requires additional processing, such as AI analysis, export, sync, or sharing.
Our apps are not medical devices unless explicitly stated otherwise. Any AI-generated output, reports, insights, summaries, or suggestions are provided for informational purposes only and are not medical advice, diagnosis, or treatment recommendations.
2.5 Analytics, Diagnostics, and Purchases
Our apps may rely on Apple-provided services related to analytics, diagnostics, subscriptions, testing, and app distribution, including:
Apple, App Store, StoreKit, TestFlight, iCloud, and HealthKit.
For subscriptions in some apps, we may also use Mercato.
We do not use third-party ad SDKs in our apps, and we do not display third-party advertising in our apps.
Brushes also uses optional Google Firebase Analytics and Firebase Crashlytics, as described in Section 2.3.
2.6 Data Retention for Apps
For many of our apps, most user content is stored locally on your device and remains under your control unless you delete it.
AI request content is not stored by our backend as part of normal operation (except the NOPE receipt scanning records described above), but it may be processed by third-party AI service providers according to their own systems and policies.
If you export content as PDF or TXT, those exported files remain where you choose to save, store, or share them.
Because most of our apps do not use user accounts on our own servers, there may be little or no server-side personal data for us to delete.
In Brushes, disabling analytics or crash reporting does not automatically delete data previously received by Google Firebase. For requests concerning information we control, contact hello@artcoastdesign.com.
For Brushes, Google Analytics is configured to retain event-level data for 2 months and user-level data for 14 months. The user-data retention period resets when new activity is recorded. These settings do not apply to aggregated standard reports. Firebase Crashlytics retains crash reports and associated identifiers for 90 days before starting their removal from live and backup systems.
2.7 Children’s Privacy in Apps
Our apps may be used by a general audience, including users under 13 in some cases. Most apps do not require account creation.
If a parent or guardian believes that a child has submitted personal information to us through an app or another service under our control, they may contact us and we will review and delete the information where applicable.
