Privacy-first by design.

Simple Reminder: Tasks is designed to function without collecting personal data or transmitting private user information to StakhivLabs or third parties.

Any reminder content, categories, and related app data remain on the user's device, unless the user independently chooses to back up, sync, or export data through services outside of StakhivLabs.

We do not use the app to build user profiles, track personal behavior, or share private information with advertisers, analytics providers, data brokers, or any other third parties.

Dayvora is a personal calendar for birthdays, anniversaries, and other meaningful dates. It does not require a Dayvora account or a separate Dayvora server.

With the user's permission, Dayvora works with the system address book. Contacts remain in the address book and are not copied into Dayvora storage or transmitted to StakhivLabs. Local reminders are scheduled directly on the user's device.

Event details, custom occasions, categories, reminder preferences, gift history, child profiles, family connections, photos, and notes are stored as Dayvora app data on the user's device.

If a Dayvora PRO user enables iCloud synchronization, only the relevant Dayvora app data is synchronized through that user's own iCloud account. System contacts remain managed by the system address book and are not duplicated in Dayvora's iCloud data.

VELREN is a private personal-awareness app for understanding recurring Bluetooth observations in the context of movement and route. It does not require a VELREN account or a VELREN-operated server.

With the user's permission, VELREN uses Bluetooth, location, and motion-related information during an active session. Its analysis, session history, routes, saved perimeters, trusted devices, and monitoring preferences are stored on the user's iPhone and are not transmitted to StakhivLabs.

VELREN contains no analytics, advertising, or telemetry. Notifications and Lock Screen information are generated by the app and handled by the user's device.

Map views may load map data through Apple Maps. Apple's handling of map requests and related service data is governed by Apple's own privacy policy.

NoirLock is a zero-knowledge, local-first vault for passwords, passkeys, TOTP codes, secure notes, seed phrases, and API tokens. NoirLock does not require an account, and there are no NoirLock servers of any kind. StakhivLabs cannot access, view, or decrypt the contents of any user's vault.

All vault records are encrypted on the user's device before they are ever written to disk or synced. Encryption keys are derived from the user's master password and an independent Secret Key that only the user holds, and are stored in the device's system Keychain — never in plain files, and never transmitted to StakhivLabs.

If a user enables sync, only already-encrypted data leaves the device, and it is sent solely to that user's own private iCloud account via Apple's CloudKit. This data is never routed through, or accessible to, StakhivLabs. iCloud storage of this synced data is governed by Apple's own privacy policy.

Where Face ID or Touch ID is used to unlock the vault, authentication is performed entirely by Apple's Secure Enclave on the user's device. NoirLock never receives, collects, stores, or transmits any biometric data.

NoirLock contains no analytics, no third-party tracking, and no advertising SDKs. No usage data, vault metadata, or personal information is collected or shared with any third party.

Because NoirLock cannot decrypt vault contents, it cannot recover or delete data on a user's behalf. Users can permanently remove their data at any time by deleting records within the app, disabling iCloud sync, or uninstalling the app and removing its data from iCloud in their device's iCloud settings.

NoirLock is not directed at children under 13, and StakhivLabs does not knowingly collect personal information from children.
