Privacy policy
How DooDoo دودو handles your information when you use our app.
Last updated: June 7, 2026
Summary
DooDoo دودو (“we”, “us”) provides a vocabulary learning experience that may include
accounts, learning progress, leaderboards, challenges, referrals, and optional notifications.
The app may show ads. This policy describes what we collect, why we use it, and your choices.
It is written in plain language but is not legal advice.
Who we are
DooDoo دودو operates the Doodoo mobile application. For privacy questions
or requests, contact us at
doodoo.crp@gmail.com.
Information we may collect
Depending on how you use the app, we or our service providers may process:
- Account and profile data — such as email address and password if you sign up with email, or authentication data if you use Google or Apple sign-in; display name, profile photo if you upload one, birth date, gender, academic year or grade level, language preferences, and a referral code assigned to your account. We do not currently collect phone numbers.
- Learning activity — such as units and lessons started or completed, vocabulary practice, quiz answers and scores, hearts, streaks, learning power, challenge participation and results, and other progress signals needed to run the product and leaderboards.
- Social and competition data — such as leaderboard rank, display name, profile photo, and learning power visible to other users (global or friends scopes); referral relationships when a code is redeemed; and challenge entries derived from your activity.
- Device and technical data — such as device type, operating system version, and app version (for example to check for updates). Google Mobile Ads (AdMob) may collect device or advertising identifiers to deliver ads, subject to Google’s policies. Firebase Analytics may log screen views, sign-in method, and lesson or quiz events, linked to your account ID in release builds. Support messages may include your platform name. The app may fetch fonts from Google Fonts at runtime. Some diagnostic information helps us fix bugs or improve reliability.
- Support and communications — such as subject, message body, optional reply email, and related metadata when you submit in-app support or email us; plus in-app notification content and read or unread state.
- Push notification tokens — if you enable notifications, a token may be stored so we can deliver broadcast, challenge, or product messages through Firebase Cloud Messaging.
Some features use text-to-speech on your device; audio may be processed
locally by the operating system or platform services according to their policies.
Preferences such as theme, locale, and cached leaderboard or config data may be stored
locally on your device.
How we use information
- Provide and improve lessons, cards, quizzes, challenges, and leaderboards.
- Authenticate you, secure accounts, and prevent abuse.

- Deliver and track in-app and push notifications when you opt in.
- Send transactional or product messages (for example reminders or important service updates) when you opt in to notifications.

Google privacy policy
We do not sell your personal information. We may share data with processors strictly
to operate the app as described here, or when required by law.
Advertising
You may see ads served by Google AdMob, including banner, interstitial, rewarded video,
and app-open formats. Google and your device platform may use advertising identifiers
or attribution tools (such as SKAdNetwork on iOS) according to their own policies and
your system settings. Ad personalization and tracking choices may be available in your
device settings and through Google’s ad settings where applicable.
Photos and media
If you upload a profile picture, we process and store that image in Supabase Storage
so it can be displayed in the app and on leaderboards. You can change or remove it from
your profile settings where available. Access to your photo library is only used for
features you initiate (such as picking a profile image).
Retention and deletion
We keep information only as long as needed to provide the service, comply with law,
resolve disputes, and enforce our agreements.
You can schedule account deletion from Profile → Delete Account in the app.
Your account is scheduled for permanent deletion after a 30-day grace period. If you sign
in again before that deadline, the deletion request is cancelled. After deletion completes,
associated personal data such as progress, streaks, referrals, and profile information
is removed as described in the app.
If you cannot access the app, you may still request deletion by emailing
doodoo.crp@gmail.com. We will verify your
request where reasonable and respond within applicable timelines.
Security
We use industry-standard safeguards such as encryption in transit and access controls
appropriate to our providers. No method of transmission or storage is 100% secure;
please use a strong password and protect your device.
Children’s privacy
DooDoo is not directed at children under 13 (or the minimum age required in your region).
If you believe we have collected information from a child without appropriate consent,
contact us and we will take steps to delete it.
International users
Your information may be processed in countries where our service providers operate.
By using the app, you understand that your data may be transferred and stored outside
your country of residence, subject to appropriate safeguards where required.
Your rights
Depending on where you live, you may have rights to access, correct, delete, or export
your personal data, or to object to or restrict certain processing. To exercise these
rights, email doodoo.crp@gmail.com from the
address associated with your account when possible.
Changes to this policy
We may update this policy from time to time. We will post the new “Last updated” date
at the top of this page and, when appropriate, provide a notice in the app.
