Privacy Policy — Daily-Saily

1. Who we are

Daily-Saily (the "App") is developed and operated by Alex Shtokhov ("we", "us", or "the developer"), an independent developer. This Privacy Policy explains what personal data we collect when you use the App, why we collect it, and what your rights are.

Questions? Reach us at alexeyshtokhov29@gmail.com.

2. What data we collect

The App collects the following categories of data, all of which are necessary for it to function:

Contact Account information Your name (if you provide one) and email address. Used to create and secure your account.

Identifier User identifier An internal account ID we generate when you sign up. Used to associate your tasks, lists, and balances with your account across devices.

Content User content Tasks, checklists, notes, categories, and other content you create inside the App. Stored so you can access them from any of your devices.

Financial Financial information Balances, accounts, transactions (income, expenses, transfers), categories, and currencies you enter manually. We never have access to your bank accounts or payment cards — only the data you choose to type in.

Fitness Fitness data Steps, distance, workouts, and active calories. If you grant permission, the App reads this data from Apple Health on your device. Fitness data is used to display your daily activity widget and is stored on our servers only if you enable cross-device sync.

What we do NOT collect

Location data (precise or approximate)
Contacts from your address book
Photos, audio, or videos
Browsing or search history outside the App
Device advertising identifiers (IDFA)
Medical or clinical health records
Sensitive personal data (race, religion, political opinion, biometrics, etc.)
Payment card numbers or bank account numbers

3. How we use your data

All data we collect is used solely to provide the core functionality of the App. Specifically:

To authenticate you and keep your account secure
To sync your tasks, lists, and balances between your devices
To show your daily activity, financial overview, and planned tasks
To send you reminders and notifications you've configured
To respond to support requests, if you contact us

We do not use your data for advertising, profiling, or any form of cross-app tracking. We do not sell, rent, or share your personal data with third parties for their marketing purposes.

4. How your data is stored and protected

Your data is stored on encrypted servers hosted by Railway, a managed cloud infrastructure provider. All connections between the App and our servers use HTTPS with TLS encryption.

Passwords are never stored in plain text — they are hashed using industry-standard algorithms before being saved. Authentication tokens are stored securely on your device and rotated regularly.

Apple Health data accessed via HealthKit remains on your device unless you explicitly enable cross-device sync; in that case only the specific metrics needed (e.g. step counts, workout summaries) are transmitted to our servers, never raw health sensor data.

5. Third-party services we use

The App relies on a small number of third-party services to function:

Railway — server hosting and database infrastructure. See Railway's Privacy Policy.
Apple HealthKit — to read fitness metrics you authorize. Apple handles this data according to its own privacy policy and we cannot access HealthKit data without your permission.
Apple Push Notification Service — to deliver notifications you've configured.

We do not use third-party analytics platforms (no Mixpanel, no Amplitude, no Google Analytics), advertising SDKs, or social-media tracking pixels.

6. Data retention

We retain your data for as long as your account is active. If you delete your account, all personal data associated with it — tasks, lists, transactions, fitness data, and account details — is permanently deleted from our servers within 30 days. Backups containing your data are rotated and overwritten within 90 days.

7. Your rights

You have the right to:

Access — request a copy of the personal data we have about you.
Correct — update or correct any inaccurate data.
Delete — delete your account and all associated data at any time.
Export — receive a copy of your data in a portable format.
Withdraw consent — revoke permissions (e.g. HealthKit access) at any time from your device settings.

You can delete your account directly from the App's Settings, or by emailing alexeyshtokhov29@gmail.com with the subject line Account deletion request. We respond to all requests within 30 days.

8. Children's privacy

Daily-Saily is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal information, please contact us at alexeyshtokhov29@gmail.com and we will delete it promptly.

9. International data transfers

Our servers are located in the regions provided by Railway, which may include the United States and the European Union. By using the App, you understand that your data may be transferred to, stored in, and processed in countries other than your country of residence.

10. Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes, we'll notify you through the App and update the "Last updated" date at the top of this page. Continued use of the App after changes are posted means you accept the updated policy.
