Doska Privacy Policy

Last updated: November 15, 2026

Doska is a cut list optimizer for sheet goods, provided by Vinsho. This policy explains how the app and its website handle information. Features may vary by platform and version.

Projects and local storage

Doska stores what you enter on your device: projects and their notes, parts and quantities, sheet materials and stock sizes, edge bands, offcuts, cutting progress and settings such as units and saw kerf. Purchase status is also stored locally.

Doska has no account and no Doska server. Your projects are not sent to the developer. They leave the device only when you use a backup, export, sharing, printing or other service described below. If Android device backup is turned on for your Google account, Android may include Doska's data in that backup under Google's device-backup settings.

Doska reads files you select to import parts. Importing, layout calculations and PDF generation run on your device. When you save, share or print a cutting plan, part labels or a backup file, the destination, printer service or recipient you choose receives it under its own privacy practices.

Backup files are not encrypted by Doska. Anyone with access to a backup file can read the projects in it.

Optional Google Drive backup

You can connect Google Drive to save backups in a Doska folder in your Drive. Doska uses Google Sign-In and the limited drive.file permission, which covers only files and folders Doska creates or that you open with it. It does not request access to your other Drive files. Your Google account identifier and authorization are used to connect the chosen account and perform backups. Google receives the backup contents and ordinary connection information.

When daily backups are on, Doska writes a new backup once a day while the app is open. Turning backups off or disconnecting stops future backups but does not delete files already in Drive; manage those in Google Drive. Doska lists the latest five backups and does not delete older ones.

Doska uses Google user data only to provide the backup and restore you request, not for advertising, and does not sell it. Doska's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google's processing is covered by the Google Privacy Policy.

Purchases

Doska uses RevenueCat to manage Doska Pro. In release builds the RevenueCat SDK starts with the app and checks purchase status, even if you have not bought Pro. It uses a generated pseudonymous app user ID and processes product identifiers, purchase and transaction information, entitlement status and app and device information to validate, restore and report purchases.

Doska does not send project, part or material details to RevenueCat. Google Play processes payments; Doska does not receive your payment-card details. See RevenueCat's Privacy Policy and Google Play's policies.

Analytics, crash reports and support

Doska shows no ads. Release builds use Google Analytics for Firebase to understand app use, such as first opens, starting and finishing a cutting plan, exports, imports and purchase actions, and Firebase Crashlytics to diagnose crashes. Purchase events include the product, price and currency. These services process app-instance and installation identifiers, app and device information, usage events, approximate location derived from IP addresses and technical diagnostics. Advertising ID collection and ad personalization are disabled. Debug and test builds do not report.

Events contain no project, part or material names, sizes or notes. App-reported errors keep only the error type and stack trace. See Firebase privacy information.

If you contact support, the developer receives your email address, your message and anything you attach. Doska does not attach projects or diagnostic files to support emails. Copy customer ID copies your RevenueCat app user ID so you can include it when asking about a purchase.

Website

The Doska website uses only its own static files. It does not use cookies, sign-in, analytics or advertising scripts. Cloudflare, the host, may process IP addresses, requested URLs and ordinary request and security information to deliver and protect the site. See Cloudflare's Privacy Policy. Store, email and other external links are subject to the destination's policies.

Information is processed to provide the features you use, manage purchases, answer support requests, keep the app working and meet legal obligations. Where data-protection law requires a legal basis, this relies on performing the service you request, your consent for optional features, legitimate interests in support and reliability, or legal obligations.

The developer does not sell personal information or use it for targeted advertising. Information may be disclosed to the providers described above, recipients you choose, or where required by law or needed to protect rights and security.

Retention, deletion and your rights

Local data stays until you delete it in the app, clear app data or uninstall Doska. Deleting a project does not remove it from earlier backups, exports or files you shared; delete those separately. Disconnecting Google Drive does not delete existing backups.

Firebase keeps analytics and crash data for limited periods set by Google and the project's settings. RevenueCat and Google Play keep transaction records as needed for purchases, fraud prevention and legal obligations. Support emails are kept only as long as needed to handle the request.

You may have rights to access, correct, export or delete personal information, object to or restrict processing, withdraw consent and complain to a data-protection authority. For information the developer controls, email vinsho.read@gmail.com with the subject Doska privacy request. The developer cannot access or erase data stored only on your device or in your own Google Drive.

Children

Doska is a tool for woodworking and is not directed at children under 13. The developer does not knowingly collect personal information from children.

Security and international processing

Doska relies on Android's app storage protections and the security of the services you connect. It does not encrypt its database, backup files or exports. Protect your device and backup locations; no storage or transmission method is completely secure.

Google, RevenueCat, Cloudflare and email providers may process information outside your country under their policies and applicable transfer safeguards.

Changes and contact

This policy may change as Doska changes. The date above identifies the current version, and material changes will be announced where required.
