Privacy policy

Last updated: 2026-10-05

This policy explains how the Key of Dreams app ("the app") handles your data. In short: the app has no accounts, keeps your dream journal only on your phone, and does not send it to us.

1. Who we are

Zemyna Studio (Giedrius Kurlavičius) ("we"). Contact: support@zemynastudio.com.

2. Data that stays on your phone

• Dream journal, saved symbols and settings are stored only on your device. We cannot see them.
• Backup: Android may include the app's data in your device backup to your Google account, depending on your phone settings. This is handled by Google, not by us.
• Morning reminder is a local notification scheduled on your phone.
• Language: to choose the app language, the app reads your phone language, the country of your SIM card or mobile network and your time zone. This happens on the phone and nothing is sent anywhere.

3. Emails you send us

If you use "Report a mistake" or "Report a missing symbol", your email app opens a message to us. We receive your email address and what you write. We use it only to reply and to improve the dictionary, and we delete it when it is no longer needed, at the latest after 2 years.

4. Advertising

The free version shows ads from Google AdMob. Before ads are shown in the European Economic Area, the UK and Switzerland, the app asks for your consent using Google's consent tool. Depending on your choice, Google may use your device's advertising ID, IP address and device information to show and measure ads (personalized or non-personalized). You can change your choice at any time in the app settings. Google's privacy policy: policies.google.com/privacy. No ads are shown while you write or read your dream entries.

5. Purchases

The one-time purchase that removes ads is processed by Google Play. We do not receive your payment details.

6. What we do not do

• No analytics or tracking tools of our own.
• No accounts, no servers storing your data, no selling of data.
• Permissions: notifications (asked when you turn on the reminder), plus internet access and the advertising ID, which are used only for ads (see section 4), and your phone's screen lock, which is used only if you reset a forgotten journal PIN — the app never receives fingerprint or face data.

7. Children

The app is not directed at children under 16.

8. Your rights

Under the GDPR (and, for users in Brazil, the LGPD) you may ask us for access to, correction or deletion of the data we hold about you (in practice, only emails you sent us), and object to its processing. Write to support@zemynastudio.com. You may also complain to a data protection authority, for example the State Data Protection Inspectorate of Lithuania (vdai.lrv.lt) or the authority of your country.

Website statistics

On zemynastudio.com and nightsymbols.com we use Cloudflare Web Analytics. It works without cookies, does not collect personal data and does not track you across other websites; we only see totals, such as how often a page was viewed and which countries and browsers visitors come from. These statistics are not used in the app. Cloudflare's privacy policy: cloudflare.com/privacypolicy.

9. Changes

We will publish any changes to this policy on this page and update the date above.
