Privacy Policy for Ladna

Effective date: 27 September 2026

Last updated: 27 September 2026

This Privacy Policy explains how Ladna (“Ladna”, “the App”, “we”, “us” or “our”) collects, uses, stores and protects personal data when you use our iOS application, the related web application (where available), our website and associated services.

Ladna is a personal self-management and life planning application. It helps you organize goals, tasks, habits, moods, health-related lifestyle entries, expenses and budgets, hobbies and shared spaces, and offers optional AI features such as a weekly review and the import of handwritten planner pages.

Ladna is not a medical, psychological, therapeutic, financial, legal or other professional advice service. Content, plans, suggestions or reviews provided by the App, including AI-generated content, are for personal organization and informational purposes only.

1. Controller

The controller responsible for the processing of your personal data is:

Viktor Nazilin
Franklin-D.-Roosevelt-Straße 104
68309 Mannheim
Germany
Email: viktor.nazilin@icloud.com

If you have any questions about this Privacy Policy or how your personal data is processed, you can contact us at the email address above. We have not appointed a data protection officer because we are not legally required to do so.

2. Scope of this Privacy Policy

This Privacy Policy applies to:

This Privacy Policy does not apply to third-party websites, platforms or services that we do not control, such as the Apple App Store.

3. Summary

The following summary is provided for convenience. The full Privacy Policy below remains authoritative.

4. Data We Process

Depending on which features you use, we process the following categories of personal data.

4.1 Account and profile data

4.2 Sign in with Apple and Sign in with Google

If you sign in with Apple, Apple provides us with a unique user identifier, an identity token and, if you choose to share them, your name and email address. You can use Apple’s “Hide My Email” option, in which case we receive a relay address. When you delete your Ladna account, we revoke the connection between your Apple ID and Ladna via Apple’s token revocation interface.

If you sign in with Google, Google provides us with a unique user identifier, an identity token, your name and your email address. We do not receive your Google password. Sign-in via Google does not give Ladna access to your Google Calendar or other Google data.

4.3 Goals, tasks and productivity data

4.4 Habits

4.5 Mood, reflection and self-assessment data

These features are intended for self-organization and self-reflection only. They do not provide medical, psychological or therapeutic assessment, diagnosis or treatment.

4.6 Health-related lifestyle data

4.7 Financial planning and expense data

Ladna does not connect to your bank and does not receive any data from financial institutions.

4.8 Hobbies

4.9 Shared spaces

4.10 AI weekly reviews

4.11 Journal photos and recognized text

4.12 Subscription and purchase data

We do not receive or store your payment card details, bank details or Apple ID password. Payment is handled entirely by Apple.

4.13 Notification data

4.14 Technical and device data

4.15 Apple diagnostics

If you have enabled sharing with app developers on your device, Apple may provide us with anonymized crash reports and performance information. This is handled according to your Apple privacy settings.

4.16 Website waitlist

If you join the waitlist on our website, we store the email address you enter and the time of registration.

5. Local Encryption

Ladna encrypts selected user-generated text on your device (AES-256) before it is stored in our database. The encrypted content is stored in fields such asencrypted_payload, and the original text columns contain only a placeholder such as[encrypted].

This currently includes, for example:

Not all data is encrypted. Metadata that the App needs for synchronization, filtering and statistics remains unencrypted, for example dates, completion status, life areas, categories, amounts, calorie values, minutes, water quantity, importance values, IDs and timestamps. Account data, subscription data, push tokens and shared-space membership data are also not encrypted on the device. Local encryption reduces the amount of readable content in our backend but does not make the data anonymous.

6. Purposes of Processing

Website waitlistConsent, Art. 6(1)(a)

Where we rely on consent, you can withdraw it at any time with effect for the future. Withdrawal does not affect the lawfulness of processing before withdrawal.

8. AI Weekly Review

The AI weekly review summarizes your week (what went well, what got in the way, a focus for next week) and suggests tasks. It is optional and is only created after you have given your consent in the App.

The weekly statistics are calculated on your device. To create the review, the App decrypts the relevant content locally and sends the following data via our server function to OpenAI:

Not sent: mood notes, well-being or self-assessment answers, health-related entries and financial data. Your email address and name are also not sent.

The data is processed by OpenAI in the USA via the OpenAI API. According to OpenAI’s terms for API customers, data sent via the API is not used to train OpenAI’s models; OpenAI may retain it for up to 30 days to detect abuse. Our server function does not store the decrypted input. The finished review is encrypted and stored in our database. You can generate or refresh a review up to three times per week.

AI-generated content may be inaccurate or incomplete. It does not constitute professional advice. The AI weekly review does not make decisions with legal or similarly significant effects on you (Art. 22 GDPR). You can use Ladna without AI features. To withdraw your consent, contact us by email; we will then stop creating reviews for you.

9. Journal Photo Import (OCR)

You can photograph a page of a paper planner, diary or notebook to turn handwritten entries into tasks. When you start an import:

Please only photograph pages that you need for the import and avoid pages containing information about other people, health information, payment card details or identity documents.

10. Ladna Premium Subscription and Payments

Ladna is offered as an auto-renewable subscription (“Ladna Premium”) with a free trial for eligible new subscribers. Purchases are made via Apple’s In-App Purchase system. Apple processes the payment as the seller and handles billing, renewals, cancellations and refunds. The processing of your data by Apple is governed by Apple’s privacy policy (apple.com/legal/privacy).

We use RevenueCat (RevenueCat, Inc., USA) to validate purchases and determine whether your account has access to Ladna Premium. For this purpose, RevenueCat receives your Ladna user ID, App Store transaction and subscription data, the storefront country and basic device information (for example platform, operating system and app version) and IP address. RevenueCat acts as our processor. More information: revenuecat.com/privacy.

Some accounts may be granted free access (for example early users). This is stored as a flag on your account.

Important: deleting your Ladna account does not cancel your subscription. Please cancel it in your Apple ID settings (Settings → [your name] → Subscriptions).

11. Reminders and Push Notifications

Ladna asks for your permission before sending notifications. You can change this at any time in iOS settings and adjust individual reminders in your Ladna profile.

We use Firebase exclusively for push delivery. We do not use Firebase Analytics or any other Firebase tracking features. Push tokens are deleted when you delete your account or when they become invalid.

12. Shared Spaces

You can create shared spaces (for example for your household, family or a trip) and invite other Ladna users by email. Content that you add to a shared space — such as tasks — is visible to all members of that space according to their role. Your name or email address may be visible to other members. Please only invite people who agree to it and only share content in a space that you want its members to see.

If you invite someone, we process their email address to deliver and display the invitation. If they do not accept, the invitation can be declined or deleted.

13. Mood, Well-being and Health-Related Data

Mood entries, reflections, self-assessment answers and health-related lifestyle entries (meals, water intake, calories) can be sensitive. We use them only to provide the features you choose to use, such as tracking, progress views and reports. Notes and answers are encrypted on your device; numeric values and dates remain unencrypted because the features need them.

This data is not sent to AI providers. Ladna does not diagnose, treat, prevent or monitor diseases and is not a medical device, therapy or counselling service. If you have medical or psychological concerns, please consult a qualified professional.

14. Financial Entries

Expense, income and budget entries are entered manually by you and serve personal organization only. Transaction notes and shopping item texts are encrypted on your device; amounts, dates and categories remain unencrypted because they are needed for statistics. Please do not enter payment card details, bank credentials or identification numbers. Ladna does not provide financial, tax or legal advice.

15. Google Calendar Integration

The Google Calendar integration is not available in the current version of the App. If we enable it in a future version, the following applies:

Ladna’s use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Data from Google APIs is not used for advertising, not sold, not transferred to third parties except as necessary to provide the feature, not used to train AI models and not read by humans except with your consent, for security purposes or where required by law.

16. Service Providers

We use the following service providers. Where they act as processors, we have concluded data processing agreements with them.

17. International Data Transfers

Some providers process data in the USA or grant access from there. Where the provider is certified under the EU-U.S. Data Privacy Framework, the transfer is based on the European Commission’s adequacy decision (Art. 45 GDPR). Otherwise, we rely on Standard Contractual Clauses (Art. 46(2)(c) GDPR) and additional safeguards. For the AI weekly review, the transfer to OpenAI is additionally covered by your consent. You can contact us for more information.

19. Account Deletion

You can delete your account at any time in the App (Profile → Delete account). This permanently deletes your account and the content associated with it, including encrypted content, weekly reviews and push tokens. If you signed in with Apple, we also revoke Ladna’s access to your Apple ID. Content you created in spaces owned by others may be removed or remain in the space without your association, depending on the space.

Deleting your account does not cancel an active Ladna Premium subscription — please cancel it in your Apple ID settings. Backups are overwritten according to our provider’s backup cycle.

20. Data Export

In your profile you can export a copy of your main data (goals, tasks, mood entries, expenses and weekly reviews) as a file. Encrypted content is decrypted on your device for the export. For a complete copy of all data we hold about you, contact us by email.

21. Your Rights

To exercise your rights, contact us at viktor.nazilin@icloud.com. We may need to verify your identity. The supervisory authority responsible for us is:

Ladna is not intended for users under the age of 16. We do not knowingly collect personal data from children under 16. If you believe a child has provided us with personal data, please contact us.

23. Security

No system is completely secure. Please keep your login credentials and your device secure.

24. Analytics and Tracking

The App does not use analytics, advertising or tracking SDKs and does not track you across apps or websites owned by other companies. Our website does not use cookies for tracking. If this changes, we will update this Privacy Policy and ask for your consent where required.

25. Changes to This Privacy Policy

We may update this Privacy Policy if we change features, providers or processing activities, or if the law changes. The current version is always available in the App and on our website. We may inform you in the App about material changes.
