Your data.
Your workbench.

The short version

This policy describes data used by HideNest: Leather Layout and its optional AI service. Local remnant planning and the current AI assistant work without an account. HideNest does not sell your data, use advertising trackers or upload your workshop to a project-sync service.

Purchasing Pro uses Apple and RevenueCat. Choosing the AI assistant sends the request you approve to HideNest’s hosted service and a third-party AI provider. These online features process the data described below.

Your workshop stays on your device

Remnant photographs, calibration measurements, traced boundaries, defect outlines, pattern geometry, projects and computed layouts are stored and processed locally on your iPhone. The layout search and geometry validation run on the device.

The app uses camera or photo access when you choose to capture or select a remnant image. It reads a file when you choose to import an SVG or workshop backup. These actions do not automatically upload the selected content to HideNest.

Apple device backups may include local app data, depending on your settings. PDFs and workshop backups are exported only when you choose to share or save them; the destination you select controls those copies.

Purchases

Apple processes payments and transaction records. RevenueCat helps the app determine whether Pro Lifetime is unlocked and restore that entitlement. This can involve a pseudonymous app-user identifier, purchase history, transaction identifiers and product information, along with technical information used to process the purchase. Purchase information is also processed for purchase analytics, such as reporting sales and entitlement activity. It is not used for advertising tracking by HideNest.

HideNest does not receive your payment-card details. Remnant photographs, outlines and pattern files are not sent to Apple or RevenueCat by the purchase integration. RevenueCat’s purchase identifier is separate from the identifier used for the AI request allowance.

See Apple’s privacy policy and RevenueCat’s privacy policy for their processing.

Optional AI requests

The AI assistant is optional and does not require sign-in. Before each request, you allow its contents to be sent over HTTPS to HideNest’s service and a third-party AI provider. The app displays the data being sent.

Your message

The text you enter to describe your batch, up to 2,000 characters.

Pattern metadata

Pattern IDs, names, width and height in millimeters, quantities, rotation rules and priority flags.

Current result statistics, when valid

Placed and unplaced counts and coverage percentage calculated on the iPhone.

Remnant photographs, traced outlines, cutting coordinates, project names, purchase identifiers and the installation identifier used for the allowance are not included in the request sent to the AI provider. Do not put personal information or confidential material in messages or pattern names if you do not want it sent for processing.

Our application backend does not store AI prompts or generated drafts as conversation history. The draft is returned to the app for review. If you apply it, the resulting batch settings become part of your local project.

The AI provider processes requests under its own terms and privacy policy. This policy does not promise that the provider retains no data or never uses data for its own stated purposes. Review the applicable AI provider privacy policy before choosing the assistant.

AI service operation

The current assistant creates no AI account and does not ask for your Apple identity, name or email. The app generates a random installation identifier and stores it in the iPhone’s Keychain. It sends that identifier to HideNest’s service when you make an AI request, so the service can enforce the daily allowance. Keychain storage can persist beyond app removal.

The service derives pseudonymous values from the installation identifier and the connection’s IP address to enforce installation, network and service-wide request limits. Its allowance database stores those values with request counters, rather than the raw installation identifier or IP address. The daily counters expire automatically within 48 hours of their creation. They do not contain messages, pattern metadata or generated drafts.

Hosting and storage providers process the information needed to operate these features, and may process technical connection or security logs such as IP addresses, timestamps, request paths and response status. Processing may occur outside your country. HideNest does not use those records for advertising.

Earlier builds: versions that offered Sign in with Apple for AI used a separate pseudonymous account identifier, encrypted Apple authorization credentials and sessions stored securely in Keychain. They did not request name or email scopes or store the raw Apple identifier in the account database. Those account records can remain until deleted; sessions expire after up to 30 days unless refreshed. The current account-free mode does not automatically delete any earlier account.

Your controls and deletion

• Access or keep a copy: view your projects in the app or use Settings → Export complete workshop backup.
• Delete local workshop content: use a project’s delete control or Settings → Delete all local projects and patterns. Removing the app also removes its local app data; the Keychain identifier and any earlier AI account are separate. Manage exported files and device-backup copies separately.
• Control future AI sharing: leave request consent off and continue with the manual batch controls. No AI account needs to be created or deleted to use the current assistant. The service’s daily allowance records expire as described above.

Earlier builds with AI accounts: their Sign out control ends the current session without deleting the account. Their Delete AI account control requests revocation of the Apple authorization and deletion of the account and its sessions. Check that deletion confirms success. If Apple or storage is unavailable, deletion can remain pending; the account is blocked for AI and deletion must be retried using that build’s account controls. Pseudonymous abuse-prevention counters and a deletion timestamp can remain for up to 48 hours. Uninstalling or upgrading alone does not request account deletion.

Deleting local content or an earlier AI account does not refund a purchase or erase records Apple or RevenueCat retain under their own policies. You may have additional data rights under the laws that apply to you.

Instructions for local controls are available in the support guide. Payment records and refund requests are managed through Apple.
