SketchOn Privacy Policy

SketchOn Privacy Notice
Last updated: November 12, 2026

Who we are
SketchOn is developed by Anthony Chase. This notice describes the SketchOn app for iPhone, iPad, and Mac. For privacy questions or requests, email checkonapp@outlook.com. For technical support, email chase-on@outlook.com.

Your library
SketchOn stores files you import, sketches, pasted text and images, previews, revisions, and settings on your device. It accesses files you choose through Files, a share action, drag and drop, or a paste action. It does not scan your photo library or read your clipboard in the background.

iCloud sync
When an iCloud account is available, SketchOn automatically syncs your library using Apple's CloudKit private database under that account. This includes originals, drawing data, previews, attachments, file names, revision identifiers, timestamps, and device type. Apple processes this data under its own terms and privacy policy. We do not operate a separate server for your library and cannot browse your private CloudKit records. SketchOn does not receive your Apple Account password.

Local sketches can be created without an iCloud account. Local drafts are adopted into the first verified iCloud account when it is safe to switch libraries. Existing libraries for different iCloud accounts are stored separately on the device. Sign out of iCloud or manage SketchOn's iCloud access in system settings to change availability of sync.

Live drawing
With local network permission, SketchOn can discover your nearby devices and send live drawing updates between them. The devices authenticate using a key associated with the sketch and encrypt live drawing messages using Apple's CryptoKit framework.

Internet Live Drawing is optional and requires you to enter a relay address and access key. No relay is configured by default. Your chosen relay receives connection information, an opaque room identifier, an access credential, and encrypted messages. The relay operator may process technical information such as IP addresses under its own privacy policy. The included relay implementation forwards messages in memory. The relay access settings are stored in the device Keychain. You can remove them in Internet Live Drawing settings. Only use a relay operator you trust.

Sharing and export
Exported files and files you share are handled by the destinations you choose. Those destinations may retain their own copies. The app does not provide a public social feed or publish your sketches automatically.

Analytics and advertising
SketchOn includes no third-party analytics, advertising, or tracking SDKs. We do not sell your sketch content or use it for advertising. Apple may process service and diagnostic information under your Apple settings and its own privacy policy.

Support
If you email us, we receive your email address and any information or attachments you choose to send. We use that information to answer your request and resolve the issue. Send only information needed for support. Support correspondence is retained only as needed to handle the request, maintain necessary records, or meet legal obligations.

Retention and deletion
Your library remains on your devices and, when synced, in your private iCloud storage. Archived notes are retained until you remove them. Newly trashed notes are eligible for permanent deletion after 30 days when SketchOn runs its cleanup. You can restore notes or delete them sooner from Archive & Trash. Permanent deletion removes the note content and syncs that deletion to connected devices; a minimal deletion marker is retained to prevent an offline copy from reappearing. Offline devices apply the change after reconnecting and syncing.

Removing the app does not necessarily delete iCloud data, backups, previously exported files, or copies on other devices. Manage those separately using the relevant Apple settings or destination. Libraries previously used with another iCloud account can remain locally until app data is removed. We cannot delete private CloudKit records on your behalf because we cannot access them.

Your choices
You control the files you import, exports, local network permission, iCloud access, and optional relay settings. Use Archive & Trash to manage note deletion. Depending on where you live, you may have rights to request access, correction, deletion, restriction, or portability of personal information we hold, or to object to its use. Contact checkonapp@outlook.com to make a request. You may also contact your local data protection authority where applicable.

Security and service providers
SketchOn uses Apple system services for storage, CloudKit, networking, encryption, and Keychain. No system can guarantee absolute security. Apple, your selected relay operator, email providers, and destinations you choose may process information in other countries under their own terms and privacy notices.

Website
Official pages hosted on chase-on.com use Shopify and may include website technologies such as Google Tag Manager or hCaptcha. These services may process IP addresses, browser information, requested pages, cookies, and form submissions under the website's privacy and consent settings. Visiting a support or privacy page does not give that website access to your SketchOn library.

Changes
We may update this notice when SketchOn or applicable requirements change. The updated notice will show a revised date. Contact checkonapp@outlook.com with questions.
