Privacy Policy
Summary. Custodian does not collect or transmit your vault contents. Your records and attachments are encrypted and stored locally on your Mac. The app has no account, developer server, analytics, advertising, tracking or network access. Information you choose to send to support is used to respond to you.
1. Who we are and what this policy covers
Custodian is developed by İbrahim Yüce and published as Stargazer Apps (“we”, “us”). This policy covers the macOS app and the Custodian support and privacy pages at stargazerapps.com. It does not cover Apple’s operating systems or services, or a cloud-storage provider you choose to use; those services have their own privacy terms.
Privacy contact: [email protected].
2. Information the app processes on your Mac
Custodian processes the information you enter or import into your vault. This may include login names and passwords, one-time-password values, identity and passport details, financial and policy records, documents, notes, links, emails, API credentials, service-account files and attachments such as PDFs, images, .env files, JSON, SSH keys and certificates.
The app reads files and folders that you select through macOS file or folder pickers. Imported records, vault settings, selected-folder access bookmarks, backup status and local activity history are used to provide app features. Custodian does not send this information to us or to an app server.
3. Local encryption and authentication
Vault contents and attachments are encrypted locally using AES-256-GCM. You unlock the vault with your vault password or, on supported Macs, Touch ID. Touch ID authentication is handled by macOS; Custodian does not receive or store your fingerprint or other biometric data. Custodian cannot reset your vault password or reconstruct a lost recovery key.
4. Files, imports and exports
Files you add are copied into the vault and encrypted there. Supported attachments can be previewed locally. CSV and JSON imports are processed on your Mac. JSON export is an action you initiate; if you choose to include sensitive values, the exported file contains those values in readable form. Store exported files somewhere you control and protect them appropriately.
5. Backups and cloud-synced folders
Custodian encrypts backups before writing them to a destination folder you select. That folder may be on an external drive or inside a folder synchronized by iCloud Drive, OneDrive, Google Drive or another provider. Custodian does not operate those services or upload your open vault to them. Once a backup is in a synchronized folder, the provider may process or store that encrypted file under its own terms.
6. Notifications and clipboard
Expiry and backup reminders are scheduled locally by macOS. Reminder notifications do not include record titles or field values. When you copy a sensitive value, it is placed on the macOS clipboard so you can paste it into another app; Custodian clears its copied value after the timeout you choose, when macOS permits.
7. Information we do not collect
Custodian has no user account, analytics or advertising SDK, tracking technology, developer-operated server or network entitlement. We do not receive your vault contents, file names, passwords, recovery key, clipboard contents, device identifiers or usage history from the app. We do not sell or share app data because the app does not transmit it to us.
If you enable macOS diagnostics sharing, Apple may process diagnostic information under its own settings and privacy terms. That system process is separate from Custodian’s app networking.
8. This website and support email
The support and privacy pages are hosted by Cloudflare Pages. Cloudflare may process standard connection, security and request information when a page is loaded. See Cloudflare’s Privacy Policy for details about its services.
If you email support, we receive your email address, message and any information you choose to include. We use it to answer your request and retain it only as needed to handle the conversation and keep appropriate business records. Do not email your vault, password, recovery key, credentials or sensitive documents.
9. Data retention and your choices
Vault data remains on your Mac and in backup destinations you select. You control records, attachments, exports, backups, notifications and app permissions from Custodian and macOS. Support correspondence remains in our email account until it is no longer needed for the request or legitimate recordkeeping.
10. Children’s privacy
Custodian is not directed to children under 13, and we do not knowingly collect personal information from children through the app.
11. Security and limitations
Custodian is designed to keep vault processing on your Mac, and the Mac App Store build has no network access. No software or storage medium is completely secure. Keep your Mac account protected, preserve your recovery key separately, and verify backups before relying on them. A backup folder synchronized by another provider is also subject to that provider’s service and security practices.
12. Changes to this policy
We will update the date at the top of this page when this policy changes. If Custodian’s data practices change materially, we will revise this policy and the relevant app privacy information before the change takes effect.
13. Your privacy rights and contact
Depending on where you live, you may have rights to request access, correction or deletion of personal information that we hold about you. Because vault contents stay on your Mac and are not sent to us, we cannot access or change them. For a privacy request or question about support correspondence, email [email protected].
14. Governing law
This policy is governed by the laws of the Republic of Türkiye, without limiting mandatory privacy rights that apply where you live.
