Effective from 27 October 2026
Flagnado collects no data about you or your child. It has no account, no server of its own, no ads, no analytics and no crash reports.
Everything you do in the app (answers, progress, medals and settings) stays on your phone.
Flagnado itself sends nothing over the internet. Only buying a coffee through Google Play needs it.
Coffees for the developer are optional and are bought through Google Play, which handles the payment.
If you write to us, we answer and then delete your message and your e-mail address.
Flagnado is developed and published by LightWise Labs, a business based in the Czech Republic.

The developer's full details (name and address) are on the app's page on Google Play under App support. Write to the e-mail above about anything concerning your privacy.
Flagnado stores only on your phone:
your answers in lessons, in MindScan and in the Daily Flag, and when each flag is due for review;
your progress: mastered flags, your Nemesis, the twins you mix up, your streak, medals, achievements and stamps;
your learning profile from MindScan (your type and five numbers between 0 and 100) and your settings (language, vibration, countdown, the reminders and their time);
when the app was last opened (for the note after a few days, if you switch it on) and what the home-screen widgets show;
whether a coffee has been bought on this phone.
Flagnado never asks for a name, an e-mail address, a photo, your location, your contacts or anything else that identifies you. The Mind Card shows only your type and five numbers, never a name.
We have no access to these data and the app sends them nowhere. To delete them, uninstall Flagnado or clear its data in Android's settings (Settings › Apps › Flagnado › Storage › Clear storage).
Backup. If backup is turned on in Android, your progress and settings are included in the backup to the Google account of the phone and in the transfer to a new phone, so they are not lost with the phone. Google runs this backup under that account (on Android 9 and later it is end-to-end encrypted); we cannot see it. You can turn backup off in the phone's settings and delete it in Google Drive under Backups.
Flagnado itself sends nothing anywhere: it has no server of its own, shows no ads, does not use the advertising ID, contains no analytics or crash-reporting tools and does not track you inside the app or across other apps and websites. Learning, the widget and the reminders work without the internet.
Flagnado has the internet permission for buying a coffee: Google Play handles the purchase, including its library for in-app purchases, under the Google Privacy Policy (section 4).
Flagnado is free and nothing in it is locked. Adults who would like to thank the developer can buy one to ten coffees: the Support development screen opens from the coffee cup in the top bar of the main screens or from More › For parents and supporters.
Google Play handles the purchase and the payment under Google's own terms; we never see card or payment details. Google processes the data it needs for the purchase, such as your Google account, the payment method and the order, as described in the Google Privacy Policy and the Google Payments Privacy Notice.
The app learns from Google Play on the phone only that a coffee has been paid for. It remembers this on the phone and says thank you: the Mind Card gets a golden frame, the passport a supporter's stamp and the top bar a gold flag. Google Play does not give coffees back after the app is reinstalled; the Android backup can bring the thank-you back.
With a child's account in Google Family Link, a parent approves each purchase in Google Play; the app simply waits for the answer.
Google Play gives us the order information we need for the sale, refunds and taxes (for example the order number, date, product, price and country). The legal basis is the performance of the contract and our legal obligations (Article 6(1)(b) and (c) GDPR); we keep this information as long as accounting and tax law requires.
The home-screen widget shows, as you choose, a random flag, today's flag or your Nemesis, always from the data on your phone. The daily reminder and the note after a few days without the app (two at most, then quiet until you open the app) are notifications planned on the phone; both are off until you switch them on, and on Android 13 and later the phone asks for your permission first. None of this sends anything anywhere.
You can share your Daily Flag result (a line of coloured squares) and your Mind Card (a picture) through Android's share menu. You choose where they go; they contain no name or other personal information, and we see nothing.
More › About › Contact opens your e-mail app with our address and the app's name and version as the subject. Nothing is sent until you send the e-mail yourself. The link to this policy opens it in your browser.
If you write to us, we use your e-mail address and your message only to answer you. We answer and then delete the message and the address, and we never write to you again on our own. If a child writes to us, we use the child's e-mail address only to answer that one message and then delete it (this is what the US law COPPA allows without a parent's consent). The legal basis is our legitimate interest in answering your message (Article 6(1)(f) GDPR).
Flagnado is made for everyone from 9 years up, and we treat every user as a child.
No data from your child. No account, no sign-in, no ads, no analytics and no location. Nothing your child does in the app leaves the phone, except a backup to the phone's Google account if you have it on.
No contact with strangers. There is no chat, no friends list and no way to talk to other users. Shared results and Mind Cards carry no name.
Purchases. The only thing to buy is an optional coffee for the developer. The main screens show a calm coffee cup in the top bar (no price, badge or animation) and More has a part for parents and supporters; both open a screen written for adults. Never in a lesson, after a lesson, at start-up, in a notification or in the widget, and it unlocks nothing. Flagnado never asks a child to ask a parent to pay. With Google Family Link you approve every purchase in Google Play; you can also require authentication for purchases in the Google Play settings.
Notifications. Only the daily reminder and the note after a few days, and only if you switch them on (More).
Links that leave the app. Only the contact e-mail and this policy, in More › About.
Deleting everything. Uninstall Flagnado or clear its storage in the phone's settings; delete the backup in Google Drive under Backups if you wish.
Questions. Write to play@janlochmann.com; we answer and then delete the address.
Flagnado follows the Google Play Families Policy.
Under the GDPR you have the right to access, correct and delete your personal data, to restrict or object to its processing and to data portability. Because Flagnado keeps nothing about you outside your phone, we usually hold no data about you at all, apart from an e-mail until we have answered it and the order information from Google Play. Ask us at play@janlochmann.com. You can also complain to the Czech supervisory authority, the Office for Personal Data Protection (Úřad pro ochranu osobních údajů, www.uoou.gov.cz), or to the authority where you live.
If Flagnado ever handles data differently, we will update this policy before releasing that version and change the date at the top.
