Limbica Privacy Policy

Last updated: 9 November 2026

Limbica keeps your records on your device. There is no account, no cloud copy, no ads, no analytics, no tracking and no third-party code. We don't receive what you record.

Who we are

Limbica is provided by Ready Node ("we"). This policy explains what the app does with your information. Email contact@readynodeone.com.

What the app stores and where

The app stores what you enter: journal entries, periods and cycle notes, symptoms, wellbeing check-ins, sleep, activity, meals and recipes, medications and intakes, practices, plans, questions for your doctor, partner cards and your profile, plus the photos, voice notes and documents you add. It also keeps the data it imports from Apple Health (see below).

• Records: files in the app's private storage on the device. They use iOS Data Protection at the Complete level, so they can't be read while your device is locked.
• Settings: your language, display choices and reminder switches, in the app's preferences on the device.
• Downloaded settings: the last copy of the signed settings file described under Network use. It contains nothing about you.
• Widget: the Home Screen widget reads no records. It shows the same neutral content for everyone and only opens the app.

Permissions and why

Each permission is optional and is requested only when you turn on a feature that needs it:

• Apple Health, to read the data listed below.
• Microphone, only after you tap Record, to save a voice note on the device.
• Speech recognition, only when you tap Transcribe on a voice note. Recognition runs on the device and nothing is sent to a server.
• Notifications, for the reminders you turn on, such as plans, medications, supply checks, practices and a period that may start soon. They are local notifications created on the device. No server is involved. By default the period reminder shows only a neutral text on the Lock Screen.
• Face ID or Touch ID, only if you turn on App lock. The app never receives your face or fingerprint data.

You pick photos and documents through the system picker, so the app has no access to the rest of your photo library or files. The app doesn't ask for camera, location or contacts access.

iCloud and device backups

The app doesn't use iCloud or CloudKit, and there is no cloud of ours. The app marks its record files to be left out of iCloud Backup and computer backups, so restoring a backup doesn't bring your records back. App settings, such as language and reminder switches, can still be part of a backup.

If you lose or reset your device, we can't restore your records. To keep a copy or move to a new device, save a backup archive (see How to export and delete).

Apple Health

Health access is optional and read-only. With your permission, the app reads sleep, steps, active energy, exercise time and menstrual flow. It reads when you import, or when you open the app if you turn on automatic updates. The app never writes to Health.

Data read from Health stays on your device. It isn't sent to us or anyone else, isn't given to the AI chat, and isn't used for advertising. An export or backup archive you make yourself can include it. You can stop access at any time in the Health app or in iOS Settings, Health, Data Access & Devices.

AI chat on your device

The LIMBICA AI tab answers with Apple's on-device model, on devices that support Apple Intelligence with iOS 26 or later, when Apple Intelligence is on and supports the app language. Your messages are processed only on your device and aren't sent to us or anyone else. No account is needed.

You can attach a short summary of your cycle, wellbeing, sleep or one journal entry, but only for the categories you allow in the chat settings and only after you see the exact text and tap Attach. That summary also stays on the device. Data from Apple Health, medications and your profile are never part of it. The conversation is kept only in the app's memory and is gone when you clear it or restart the app.

This version has no server AI. If Apple's model isn't available, the chat tells you why and sends nothing.

Network use

The app doesn't send your records anywhere. It has no in-app purchases in this version and makes no App Store purchase requests.

Downloads from our CDN. From time to time, for example at launch, the app makes an anonymous GET request to cdn.readynodeone.com, which is hosted on Cloudflare. It downloads one settings file that can switch individual features of the app off. These documents are signed and the app checks the signature on the device before using them. They contain data, not code.

The request sends only the app ID and the name of the download in the address, with no query values, and a cache tag (ETag) for the copy the app already has. Like any request made through iOS, it also carries standard technical headers, such as accepted languages and a user agent naming the app build and the iOS version. It does not send your records, health data, settings or any account, device or advertising identifier, and the app adds no cookies.

Your IP address reaches Cloudflare, as with any web request. We don't use it to identify anyone. Cloudflare handles such logs under its own policy: Cloudflare Privacy Policy.

Which features apply is decided on your device. The app compares the rules in the file with the app and iOS versions, the app language, the device region, the device type (iPhone or iPad), the number of days since installation and a random number that is created and kept only on your device. None of these values are sent.

Links you tap, such as this policy or our support page, open in your browser. This version doesn't open partner websites.

Sharing you choose

When you share an entry, a doctor report, a card for your partner, an image or an export, it goes only where you send it through the system Share menu. After that, the recipient controls it. The app doesn't upload anything you share.

Analytics and tracking

The app has no analytics, crash reporting, advertising or tracking code. It doesn't count or record how you use it, and it doesn't track you across apps or websites.

If you turned on sharing with app developers in your iOS analytics settings, Apple may give us crash reports and usage statistics under Apple's own terms. They don't contain your records.

Third parties

The app contains no third-party SDKs or code libraries. The outside services involved are Apple (App Store, Health, the on-device model, and backups if you use them) and Cloudflare (the download above).

App Store. Limbica is free and has no in-app purchases in this version. Apple distributes the app under Apple's privacy policy and gives us App Store reports, such as download numbers by country. We don't receive your name or your Apple Account details. We can also read public App Store reviews, as anyone can.

We don't sell personal data and we don't share it for advertising.

How long data is kept

Your records stay on your device until you delete them or delete the app. With Automatic deletion, which is off until you turn it on, entries older than 1, 2 or 5 years are deleted on the device.

If you email us, we receive your address and whatever you write or attach, and our email provider handles the message. We use it only to answer you and keep it only as long as that takes, unless you ask us to delete it sooner.

How to export and delete

These are in Settings (the gear on the Today screen), then Privacy and data:

• Privacy and export: creates a JSON file with all the data of the categories you pick, or CSV spreadsheet files. These files aren't encrypted.
• Backup archive: a full copy you can restore on this or a new device. Photos, voice notes and document files are included only if you turn them on. You can protect it with a password: the archive is then encrypted on your device with AES-256-GCM, using a key derived from your password. The password isn't stored anywhere and we can't recover it, so without it nobody can open the archive. An archive without a password isn't encrypted.
• Delete data on this device: deletes everything, or only the sections you choose, after you confirm by typing a word. Deletion runs the next time you open the app and can't be undone. Choosing everything also deletes app settings (your language choice can stay) and temporary copies. It doesn't touch data in Apple Health, files you already shared or saved elsewhere, or the downloaded settings file, which holds nothing about you.
• Automatic deletion: deletes entries older than the period you choose.

A doctor report (PDF) is made from your own records in Doctor preparation, in Explore. Deleting the app also deletes all its records from the device. Keep exports and archives somewhere safe, because they contain your health information.

Security

Besides iOS Data Protection, you can turn on App lock in Settings, Privacy and data. The app then asks for Face ID, Touch ID or your device passcode when you open it, and can hide its content in the app switcher. If unlocking fails, nothing is deleted or changed.

Children

Limbica isn't directed at children under 13, or the higher minimum age that applies in your country. We don't knowingly collect personal information from children. If you think a child has sent us personal information by email, contact us and we will delete it.

Your rights

Depending on where you live, privacy laws such as the GDPR in the EU and UK and the CCPA in California give you rights over your personal data: to see it, correct it, delete it, get a copy, object to or limit its use, and not be treated worse for using these rights.

We don't run accounts and we don't receive what you enter in the app, so there is no record of yours for us to look up. You use most of these rights directly in the app: view and correct your entries, export them with Privacy and export or a backup archive, and delete them with Delete data on this device or Automatic deletion.

For anything we do hold, such as an email you sent us, write to us and we will respond. You can also complain to your local data protection authority.

Changes to this policy

We update this page when the app or our practices change, and we change the date at the top. If a change matters to how your data is used, we will also say so in the app or its release notes.
