Privacy Policy

01 Scope and responsibility

This policy covers History of Bulgaria for iPhone and iPad, voluntary support correspondence and these legal pages. The publisher is Andrii Matiushev, trading as Zydeno. The publisher is responsible for personal information you choose to send in support correspondence. We have no remote access to data stored by the app on your device. Apple and external websites operate under their own policies.

02 What the app does not collect

The app does not collect or transmit personal data to us. It has no accounts, advertising, in-app purchases, subscriptions, analytics, tracking, telemetry, cloud synchronisation or publisher backend. It does not send your progress, answers, settings, identifiers or usage history over the network. It does not request access to your location, microphone, contacts, notifications or advertising identifier. There is no profiling or automated decision-making about people.

Stories, narration, images and map content are included in the installed app and work offline. Reading, listening and answering questions do not require a connection. External websites require a connection only if you choose to open them.

03 On-device storage and your choices

The app stores reading and listening position, saved-story identifiers, question responses and results, attempt and interaction dates, recent search queries, daily selections and preferences on your device. Its progress file, which also contains saved stories and settings, is stored in Application Support and marked as excluded from device backup. The onboarding-completion flag, recent searches and daily selections are stored separately in local system preferences. There is no automatic progress transfer between devices and we hold no server copy. While narration plays, the story title and playback position appear in the iOS Now Playing controls on your device.

To remove the app and its local data, delete the app in iOS or iPadOS. Offloading the app can retain its data. In Settings you can export your progress to a file you choose, import such a file, or delete all local data, and you can clear recent searches in search. An exported file is yours: it never reaches us, and where you keep or send it is your choice. We cannot restore lost local progress. Protect access to your device and exported files.

04 Actions you choose outside the app

When you tap a source or licence link, it opens an in-app Safari browser or your browser. The destination can receive your IP address and browser information and may use cookies under its own policy. The app does not contact those sites in the background.

Report an error opens your email app with the story identifier, scene identifier when available, content version and selected language prefilled. You can edit or cancel the message. Sending requires your action in the email app. We receive the email address, message and any attachments you choose to send, and use them to answer your request or correct content, not for marketing. Your email provider handles delivery under its own policy.

05 Apple diagnostics

Apple may make crash reports and diagnostic information available to developers according to your system-level sharing choices. This is handled by Apple; the app includes no analytics or crash-reporting SDK. You can manage diagnostic sharing in iOS or iPadOS Settings under Privacy & Security, then Analytics & Improvements. See Apple.

06 Support correspondence: basis, retention and security

Where applicable, answering your request relies on legitimate interests in providing support (GDPR Article 6(1)(f)), taking steps you request under a contract (6(1)(b)), or a legal obligation (6(1)(c)). Necessary local storage serves the functionality you request; it is not server-side collection. Do not send sensitive information you do not need to share.

Support messages are kept for up to 24 months after the matter closes, unless you request earlier deletion or law or the defence of claims requires longer retention. Our mail provider processes delivery and storage; messages may travel outside your country. Where required, transfers use adequacy decisions or appropriate contractual safeguards. No system is completely secure. Protect your device and exported files.

07 Your privacy rights

For personal information you send to support, contact [email protected] to exercise rights available under applicable law, including access, correction, deletion, restriction, objection and data portability. Where processing relies on consent, you may withdraw it. These rights can be subject to legal conditions and exceptions. We cannot identify or retrieve progress stored only on your device.

We do not sell personal information or share it for targeted advertising. We will respond to requests within the period required by applicable law, requesting only information reasonably needed to verify and handle the request. You may complain to your local data-protection authority. In Bulgaria, this is the Commission for Personal Data Protection: cpdp.bg. Further information about EU data-protection rights is available from the European Commission.

08 Children

This is a general-audience history app, including for independent use by younger readers. It collects no personal data from anyone, including children. Where local law requires it, use should be with a parent’s or guardian’s agreement. If a child sends personal information by email, a parent may contact us to request deletion. We do not use children’s messages for marketing.

09 These pages and third parties

The generated legal documents contain local fonts and no scripts, cookies, analytics or embedded third-party resources. When you visit a hosted page, its server necessarily receives connection information such as an IP address; these documents do not control server logging or hosting infrastructure. This is separate from the offline app. Linked sites, Apple, browsers and email providers apply their own terms and privacy policies.

10 Current version and policy changes

This policy describes the current app. Any material change to data handling will be reflected in a dated policy and applicable App Store disclosures, with notice and consent where required. Contact [email protected] with privacy questions or complaints.

Version 1.0, prepared for release on 5 November 2026. This preparation date does not announce App Store availability.

11 Content and licences

Images and other materials retain the authorship, sources and individual licences identified in the app’s About and licences screen and story credits. Image terms include public-domain status, CC0, CC BY and CC BY-SA, as specified per asset. A source citation is not permission to republish its material. Cormorant Garamond, Manrope and Merriweather use SIL Open Font License 1.1; the app also includes derived fonts with accompanying notices. These web pages bundle Cormorant Garamond and Manrope with their OFL notices. Natural Earth base-map data is public domain: Natural Earth. Base-map geography does not establish historical borders. Synthetic narration is generated before distribution and bundled as audio; no voice model or speech-generation service runs in the app.
