Foldlark privacy policy

Effective November 2, 2026

Trilon Apps Private Limited builds Foldlark, a file-search utility for Mac, iPhone, and iPad. This policy describes Foldlark's handling of your information.

Your folders stay under your control

You choose the folders Foldlark may access using the system folder picker. Foldlark reads file names, folder paths, sizes, dates, and other available file metadata to provide search and sorting. It does not change or delete the original files. It does not index the text inside your documents.

Local storage

On Mac, completed search indexes are stored locally in the app's sandbox. On iPhone and iPad, version 1.1 and later also save completed search indexes on your device so the library can reopen without a full rescan. Earlier mobile versions keep the search catalogue in memory and rebuild it when needed. Saved folder-access bookmarks and preferences are stored on your device so Foldlark can reconnect to the folders you selected. The Mac command-line tool reads the same local indexes and outputs results only where you direct it.

No Foldlark data collection or tracking

Foldlark has no user account, advertising, analytics SDK, tracking system, or application server. It does not send your file metadata, search terms, document contents, or folder-access bookmarks to Trilon Apps. We do not sell this information.

Files providers, previews, and sharing

Folders provided by iCloud Drive, third-party storage services, external drives, and network servers remain subject to their own access and privacy rules. Foldlark requests available metadata without intentionally downloading document contents for indexing. Opening or sharing a cloud file may cause its provider to download it. On iPhone and iPad, Foldlark prepares temporary copies for previews and sharing, and removes those copies when no longer needed. If you choose to share a file, the recipient or service you select receives that copy.

Apple services and diagnostics

Apple distributes the app through the App Store or TestFlight and may process diagnostics according to your device and testing preferences. Apple and your chosen file providers operate under their own privacy policies.

Support messages

If you email support, we receive the address and information you choose to send and use it to respond to your request. Please do not send private documents, passwords, or tokens. You can request deletion of your support correspondence by contacting us.

Your choices

You can remove a saved folder from Foldlark and control access through system settings. Removing the app does not remove your original documents. Device backups and cloud-provider copies are managed by you and the relevant operating system or provider.

Changes and contact

We will update this page and its effective date when these practices change. Questions about Foldlark privacy can be sent to support@trilonapps.com.
