This Privacy Policy explains how HumanKind Systems LLC (“Company,” “we,” “us,” or “our”) handles information when you use the anti-diary mobile application (“App” or “Service”).
the anti-diary is designed to give users a private place to write, release, and optionally keep personal entries without requiring an account.
We do not require you to create an account to use the App.
By using the App, you acknowledge this Privacy Policy.
This Privacy Policy explains what information may be stored, processed, or received when you use the anti-diary.
The App is designed so that HumanKind Systems LLC does not operate a server that receives or stores the private content you write in the App.
Certain App content is stored locally on your device. Saved Entries may also be stored or synchronized through Apple services such as iCloud and CloudKit, depending on your device, Apple ID, iCloud availability, and system settings.
HumanKind Systems LLC does not receive your journal entries, unsent messages, unsent email drafts, or voicemail recordings on our own servers.
Depending on the feature you use, the App may store information such as:
Temporary drafts and recordings are used to provide the App's features and recovery behavior. HumanKind Systems LLC does not use the content of your private writing or recordings for advertising, profiling, marketing, or behavioral tracking.
The App does not currently require you to create an account.
Because there is no HumanKind Systems account system for the App, we do not collect account usernames, account passwords, or profile information through an Anti-Diary account.
Temporary drafts, preferences, and other App state may be stored locally on your device.
Saved Entries may also use Apple’s iCloud and CloudKit services to support storage and synchronization across compatible devices when those services are available and enabled.
Data stored in a user's private CloudKit database is managed through the user's Apple iCloud account. HumanKind Systems LLC does not operate its own server for storing or reading your Saved Entry content.
Apple may also include certain App data in device or iCloud backups depending on your Apple settings. HumanKind Systems LLC does not control Apple’s iCloud, CloudKit, or backup systems.
You can review and manage relevant iCloud and backup settings through your device settings.
The App allows you to protect Saved Entries using available device security or a custom PIN or password.
Custom PINs and passwords are not stored by the App in readable form. The App stores protected verification information using Apple Keychain services on the device.
If you use device authentication, Apple system features such as Face ID, Touch ID, Optic ID where supported, or the device passcode may be used to confirm device ownership. HumanKind Systems LLC does not receive your biometric data.
The App may request microphone access if you choose to use the voicemail-style feature in the Unsent Pack.
Microphone access is used to allow you to record an unsent voicemail within the App.
HumanKind Systems LLC does not receive, store, or listen to your voicemail recordings on our servers.
Voicemail recordings created for this feature are temporary and are removed as part of the App's send, reset, or cleanup flow.
You can disable microphone access at any time in your device settings.
The App may offer non-subscription, one-time in-app purchases, including optional feature upgrades.
Payments are processed by Apple through the App Store. HumanKind Systems LLC does not receive or store your payment card number, bank account information, or other direct payment credentials.
We use RevenueCat, a third-party purchase-management service, to verify purchases and determine whether purchased features should be unlocked.
In connection with this service, RevenueCat may process purchase-history, transaction, entitlement, receipt, and limited technical information needed to provide purchase functionality and related purchase analytics.
This may include information such as an Apple purchase receipt, purchase status, entitlement information, device type, operating system, and related transaction information.
RevenueCat does not receive the private journal entries, unsent messages, unsent email content, or voicemail content you create in the App through our RevenueCat integration.
RevenueCat processes information according to its own privacy practices.
We may receive limited personal information if you contact HumanKind Systems LLC directly for support, feedback, or another business-related reason.
This may include:
We use this information to respond to your request, troubleshoot issues, provide support, and maintain appropriate business records.
The current version of the App does not use advertising networks or third-party behavioral tracking tools.
We do not use your private writing, unsent communications, or voicemail content for advertising, behavioral tracking, profiling, or marketing.
RevenueCat provides purchase-related reporting and analytics associated with in-app purchase functionality. This is described in the In-App Purchases and RevenueCat section above.
The current version of the App does not use a separate third-party general usage analytics SDK or third-party crash-reporting SDK.
If we add advertising, additional analytics, crash reporting, new cloud services, account features, or similar tools in the future, we will update this Privacy Policy and applicable App Store privacy disclosures as needed.
The App relies on certain Apple technologies and services, which may include:
Apple's handling of information through these services is governed by Apple's own privacy policies and terms.
Our Privacy Policy, Terms and Conditions, support page, and related website pages may be hosted by a third-party website hosting provider, such as GitHub Pages.
When you visit those web pages, the hosting provider may process basic technical information such as your IP address, browser type, device information, and access logs according to its own policies.
Our legal and support pages are not used to collect the private content you create inside the App.
Where HumanKind Systems LLC receives or processes information, we may use it for purposes such as:
We do not sell your personal information.
HumanKind Systems LLC does not share your private journal entries, unsent message content, unsent email content, or voicemail content with advertisers.
Limited information may be processed or disclosed in circumstances such as:
Content stored locally in the App generally remains on your device until it is deleted through the App, removed as part of an App feature, or affected by deletion of the App or device data.
Saved Entries stored or synchronized using Apple's iCloud or CloudKit services may also be subject to Apple's storage, synchronization, backup, deletion, and retention processes.
Purchase and entitlement information processed by Apple or RevenueCat may be retained according to those providers' applicable policies and legal obligations.
Support emails and direct communications may be retained for as long as reasonably necessary to respond to your request, maintain business records, comply with legal obligations, resolve disputes, or enforce agreements.
You can delete App content directly where deletion features are available.
You may also delete the App from your device to remove locally stored App data, subject to information that may remain in Apple backups, iCloud, or CloudKit according to your Apple account and device settings.
If you have contacted HumanKind Systems LLC directly and want us to delete personal information you provided through a support communication, you may contact us using the email address below.
We use reasonable measures appropriate to the nature of the App and the information involved. However, no method of electronic storage or transmission can be guaranteed to be completely secure.
Device-level security is important for protecting information stored in the App. The App offers optional Saved Entries protection, and we encourage users to maintain appropriate iPhone security settings.
The App is not directed to children under 13.
HumanKind Systems LLC does not knowingly collect personal information directly from children under 13 through an App account system.
If you believe a child under 13 has provided personal information directly to us, please contact us and we will take appropriate steps consistent with applicable law.
If you are under the age of majority in your jurisdiction, you should use the App only with any permission required by applicable law.
California residents may have privacy rights under applicable California law, including rights relating to access, correction, deletion, and certain uses or disclosures of personal information.
HumanKind Systems LLC does not sell personal information or share personal information for cross-context behavioral advertising.
Because HumanKind Systems LLC does not operate a server that receives your private Anti-Diary writing content, requests concerning locally stored App content can generally be managed directly through the App or device.
Information maintained through Apple services or RevenueCat may also be subject to the privacy controls and rights processes offered by those providers.
To make a privacy request concerning personal information you have provided directly to HumanKind Systems LLC, contact us using the email address below.
Depending on where you live and applicable law, you may have rights concerning personal information held about you, which can include rights to access, correct, delete, restrict, object to certain processing, or request a copy of information.
To exercise a privacy right concerning information held directly by HumanKind Systems LLC, contact us using the email address below. We may need to verify your request before responding.
The App or our website pages may contain links to websites or services not operated by HumanKind Systems LLC.
We are not responsible for the content, privacy policies, or practices of independent third-party websites or services. You should review the privacy practices of services you choose to use.
We may update this Privacy Policy from time to time to reflect changes in the App, our practices, legal requirements, or third-party services.
When we update this policy, we will revise the “Last updated” date at the top of this page.
Changes become effective when posted unless otherwise stated.
