Pikura ("the App") is a drawing and coloring application for children and adults, developed by NTVTech. This policy explains which data stays on the device, which third-party services receive data from the App, and the choices available to parents.
Some technical data, such as the IP address and device information, is received by the third-party service providers listed in section 4.
The following data is stored ONLY on the user's device and is never transmitted to our servers:
The table below is the complete list of third parties that receive any data from the App. None of them receives the drawings, photos, display name or anything else created in the App. Each provider handles data under its own privacy policy.
| Provider | Purpose | Data received | Privacy policy |
|---|---|---|---|
| Google Firebase Analytics | Anonymous, aggregated usage statistics from standard events that Firebase collects automatically (such as app opens, sessions and app updates). The App sends no custom events. Firebase also automatically logs in-app purchase events (the product purchased, its price and currency). | Installation and device identifiers used only for analytics (not advertising identifiers), device model, operating system and app version, language, and approximate country or region derived from the IP address. | firebase.google.com/support/privacy |
| Google Firebase Crashlytics | Crash reports, used only to fix stability problems. | Technical crash details (error message and stack trace), device model, operating system and app version, and a Crashlytics installation identifier. | firebase.google.com/support/privacy |
| Google Firebase Remote Config | Downloading app settings, such as free-version limits and maintenance or update notices. | A Firebase installation identifier, app version, platform, and language or country. | firebase.google.com/support/privacy |
| Google AdMob | Optional rewarded video ads in the free version only (see section 5). The ad SDK is not started for Pikura Plus subscribers. | IP address, device and operating system information, language, app information and interactions with the ad. The App never asks for tracking permission on iOS and has no access to the advertising ID on Android, so it provides no advertising identifier. Google does still receive device identifiers that are not advertising identifiers, such as the identifier for vendors (IDFV) on iOS and app instance identifiers set by the ad SDK. Depending on consent choices (see section 5) and local law, Google may use this data to personalize ads. This personalization applies only to the Adult profile; for the child profiles (Mini and Junior), requests are tagged for child-directed treatment and ads are not personalized. On iOS, ads are not personalized in any profile. | policies.google.com/technologies/partner-sites |
| Qonversion | Validating subscriptions and restoring purchases. | Purchase and subscription status from the store, the anonymous installation identifier described below, device model, operating system and app version, and IP address. No name, email address or payment card details. | qonversion.io/privacy |
| Apple App Store / Google Play | Payments, subscription management and the optional rating prompt. | Handled under your own store account. We never receive payment card details. | www.apple.com/legal/privacy/ policies.google.com/privacy |
| GitHub Pages (GitHub, Inc.) | Hosting the latest version of these legal documents, which the App loads when you open them. | IP address and technical request data, as for any website. | docs.github.com/en/site-policy/privacy-policies/github-general-privacy-statement |
| Google Fonts | Downloading a font, only when a parent exports a PDF that contains Chinese, Japanese or Korean text. | IP address and technical request data, as for any website. | policies.google.com/privacy |
Only the providers above receive data. Components that run entirely on the device (for example the AI models used by Photo Magic, the drawing tools and local notifications) send nothing anywhere. If we add or change a provider, we will update this section.
To let a purchase be restored, the App creates a random identifier that is not linked to a name, email address, device or advertising identifier, and shares it only with Qonversion. On iOS it is kept in the device Keychain, which is not removed when the App is uninstalled, so a purchase can still be recognized after reinstalling; it is not synced through iCloud. On Android it is removed when the App is uninstalled.
The free version of the App shows only optional rewarded video ads. A video plays only when a user taps to watch one in exchange for a small reward, for example one extra Photo Magic use, more Gallery space, the special brush set for the current drawing session, a streak freeze, or temporary access to a coloring page. The App does not show banner ads, interstitial (full-screen pop-up) ads or ads placed among content. Ads are:
Pikura is made for both children and adults. Parents or guardians should supervise young children when they use the App. The profile chosen during setup (3-5, 6-11 or Adult) is stored only on the device and is used only to adapt the App and to decide how ads are requested (see section 5).
In the child profiles, a parental gate (a multiplication question, or an optional parent PIN) protects purchases, the Parent Zone, sharing and exporting artwork, and deleting artwork. The Adult profile skips the parental gate; switching to it requires passing the gate once. In the Parent Zone, parents can:
Ads are optional. Watching a rewarded video is not protected by the parental gate, because it is not a purchase. A parent who does not want a child to see ads can subscribe to Pikura Plus, in which case the ad SDK is not started at all, or make sure the child does not choose the optional offers to watch a video.
All app data (drawings, photos kept for Photo Magic, progress, settings and display name) can be deleted through Parent Zone > Delete All Data. Uninstalling the App also removes this data from the device. On iOS, the anonymous installation identifier described in section 4 stays in the Keychain so that purchases can be restored after reinstalling; it contains no personal information.
Drawings, photos and personal settings remain on the device. No cloud accounts or logins are required. Premium purchases are tied to your App Store or Google Play account; Qonversion receives only the anonymous installation identifier described in section 4, never a name or email address. Data sent to the service providers in section 4 travels over encrypted (HTTPS) connections.
We will notify users of significant changes through an in-app notice. Continued use after changes constitutes acceptance.
