Privacy Policy for ProVocab

Last Updated: October 2, 2026

ProVocab is a vocabulary flashcard app made by PrSeo7, an independent developer. This page explains what data the App handles, why, and what you can do about it. PrSeo7 is the data controller for the processing described here; contact: hello.prseo7@gmail.com.

The short version

The App has no user accounts. It never asks for your name, e-mail address or any other personal detail.
Your learning progress and settings stay on your device. We run no server and receive no copy of them.
The App uses Google’s Firebase for usage analytics and crash reports, and, for ads in the free version only, Unity’s ad networks Unity Ads and ironSource Ads plus Meta Audience Network, all through Unity LevelPlay. Analytics and crash data go from your device straight to Google; advertising data goes straight to Unity and Meta.
Because we hold no identifier for you, we cannot look up or delete an individual’s analytics or crash records. They expire automatically, and uninstalling the App stops all collection.
Buying Premium (a one-time purchase, no subscription) removes ads and all advertising data collection.

What the App collects

Usage analytics (Firebase Analytics, all users)

Device model and operating system version
A Firebase installation identifier that Google assigns to this installation (it changes if you reinstall); on iOS also Apple’s identifier for vendors (IDFV), which is shared by all PrSeo7 apps on your device
How you use the App: review sessions and each review result (whether you remembered or forgot a word), study-streak milestones, theme changes, whether banner ads loaded and were shown, taps on the “More by PrSeo7” links, opening the study calendar (with the number of days you have studied), and purchase or restore events, including the price, the currency and the store’s transaction number for the Premium purchase
Your premium status and app theme
Approximate location at country/region level, which Google derives from a masked IP address. This applies to all users, including Premium. The App requests no location permission and never uses your device’s location services
Firebase Analytics does not collect the Android advertising ID. On iOS the advertising identifier is available to Google only if you allowed tracking in the iOS tracking prompt

Crash reports (Firebase Crashlytics, all users)

Crash logs and stack traces, errors reported by the app framework, the device state at the time, and an installation identifier used to count affected devices

Advertising (Unity Ads, ironSource Ads and Meta Audience Network, through Unity LevelPlay; free version only)

The device advertising ID (on iOS only if you allowed tracking for the App; on Android according to your device’s ad settings, and Unity chooses ads without it if you chose non-personalized ads), your IP address (Unity may estimate an approximate location from it), device information, which ads were shown or tapped, and diagnostic data about the ad software. This applies on both iOS and Android
Advertising data is collected only while ads are shown, never for Premium users, and starting from the first screen that shows an ad, not at launch. On Android, copies of the App running on Google Play’s pre-launch test devices or installed from outside the Play Store show no ads
On iOS, ad-driven installs may be attributed through Apple’s SKAdNetwork, which does not identify you

Fonts

The App downloads its display fonts from Google Fonts the first time they are needed, so your IP address reaches Google’s font servers

On your device only

Words you mark as learned, your review schedule, streaks, starred words, and your language, theme, haptics and reminder settings. This data is stored in the App’s own storage on your device; it is included in your device’s normal system backups (iCloud or Google backup) if you have those turned on. “Export Progress” writes it to a file that you choose where to send; “Import Progress” reads such a file back through the system file picker and merges it into your progress. Backups contain only learning progress, no identifiers

Purchases

The Premium purchase is processed by Apple or Google Play. We never see your payment details; the App only learns whether Premium is owned. The App may also ask the store to show its standard rating prompt

Reminders

If you turn on the daily reminder, the App schedules one local notification per day on your device at about the time you choose. There is no push server and nothing is sent anywhere. Notification permission is requested only when you turn reminders on

Why, and on what legal basis

What	Why	Legal basis (EEA, UK, Switzerland)
Learning data on your device	Provide the App	Not processed by us
Analytics and crash reports	Understand usage, fix crashes	Legitimate interests (GDPR Art. 6(1)(f))
Personalized ads (free version)	Fund the free version	Your consent (Art. 6(1)(a)), given in the iOS tracking prompt (iOS) or the App’s consent sheet (Android; there it applies to Unity’s networks, because on Android Meta Audience Network does not serve ads in the EEA, the UK and Switzerland)
Ads in general (free version)	Fund the free version	Legitimate interests (Art. 6(1)(f))
Font download	Display the App’s text	Legitimate interests (Art. 6(1)(f))
Premium purchase	Unlock Premium, restore it later	Contract (Art. 6(1)(b))

We make no decisions about you based solely on automated processing that have legal or similarly significant effects. Nothing here is required by law or contract; if you do not want this processing, use Premium (no advertising data) or uninstall the App (no collection at all).

Who receives data

Only these companies receive data from the App, each bound to protect it at least as well as this policy says:

Google LLC (Firebase Analytics, Firebase Crashlytics, Google Fonts): https://policies.google.com/privacy and https://firebase.google.com/support/privacy
Unity Technologies (Unity Ads, ironSource Ads, Unity LevelPlay; free version only), which decides itself how it uses advertising data and may share it with its affiliates and ad partners as its policy describes: https://unity.com/legal/game-player-and-app-user-privacy-policy
Meta (Meta Audience Network, through Unity LevelPlay; free version): Meta Platforms Ireland Limited for users in the EU/EEA and Meta Platforms, Inc. elsewhere, including the UK, each a data controller of the data it receives. On Android, Meta Audience Network does not serve ads to users in the EEA, the UK and Switzerland. Meta decides itself how it uses advertising data and may combine it with what it knows about Facebook and Instagram users to personalize ads (on iOS it receives the advertising ID only if you allow tracking; on Android according to your device’s ad settings): https://www.facebook.com/privacy/policy/
Apple and Google Play for the Premium purchase and the store rating prompt: https://www.apple.com/legal/privacy/ and https://policies.google.com/privacy

Google, Unity and Meta process this data in the United States and other countries. For users in the EEA, the UK and Switzerland, Google relies on the EU-U.S. Data Privacy Framework and the EU Standard Contractual Clauses (https://policies.google.com/privacy/frameworks); Unity relies on the Standard Contractual Clauses and on adequacy decisions; Meta relies on the EU-U.S. and Swiss-U.S. Data Privacy Frameworks (https://www.facebook.com/privacy/policies/data_privacy_framework/) and the Standard Contractual Clauses, with the UK addendum for the UK (https://www.facebook.com/legal/terms/uk_data_transfer_addendum_audience_network). No data is transferred to us.

Your choices

Ad consent (everyone): before the first ad, the App asks how ads are chosen. On iOS, an information screen with a “Continue” button is followed by the iOS tracking prompt (unless you already answered the iOS tracking prompt): “Allow” means personalized ads, “Ask App Not to Track” means non-personalized ads; change it at any time in iOS Settings > ProVocab > “Allow Tracking” (the App’s Settings > Privacy > “Ad Privacy Settings” shows the current state, “Personalized ads: allowed” or “Personalized ads: not allowed”, and an “Open Settings” button that links there). On Android, a sheet titled “Ads in the free version” asks you to choose between “Personalized ads” and “Non-personalized ads”; change it under Settings > Privacy > “Ad Privacy Settings”. Your answer is passed to Unity’s networks (Unity Ads, ironSource Ads)
Meta (iOS): Meta follows your iOS tracking permission, which its software reads itself on iOS 17 and later; on earlier iOS versions the App does not tell Meta that tracking is allowed, so Meta treats you as not tracked
Meta (Android): Meta Audience Network does not serve ads to users in the EEA, the UK and Switzerland. Elsewhere the App does not pass your answer to Meta, and Android has no tracking prompt, so Meta follows only your device’s ad settings (below). The App tells Meta only that it is not directed to children
Inside an ad: Unity’s Data Privacy icon lets you opt out of personalized ads with Unity directly; Meta’s ads carry Meta’s ad-options (AdChoices) icon
Android: your device’s ad settings (for example Settings > Google > Ads) let you delete your advertising ID or opt out of ad personalization; this is the setting Meta follows
Premium: removes ads and all advertising data collection
Uninstall: deletes everything stored on your device and stops all collection
Usage analytics cannot be switched off inside the App; it contains no advertising identifier unless you allowed tracking, and it is not used for advertising

How long data is kept

On-device data: until you uninstall the App
Firebase Analytics: up to 14 months, then deleted automatically
Firebase Crashlytics: 90 days, then deleted automatically
Unity Ads: app interaction data tied to an installation identifier up to 12 months; transaction records up to 180 days; other advertising data for as long as Unity needs it for the purposes in its policy (https://unity.com/legal/game-player-and-app-user-privacy-policy)
Meta Audience Network: as long as Meta needs it to provide its products, comply with legal obligations or protect its or others’ interests, decided case by case by the purpose and the feature; Meta names no fixed period (https://www.facebook.com/privacy/policy/, “How long do we keep your information?”)
Ad data collected by Google AdMob in versions before September 24, 2026: under Google’s advertising retention rules (https://policies.google.com/technologies/retention)

We cannot delete individual analytics or crash records on request: the App has no accounts, so we have no way to find the records that belong to you. That data is not linked to your identity and expires as listed above.

Your rights

Everyone: ask us what the App collects (this page is the complete answer), opt out of personalized ads as described above, and delete your on-device data by uninstalling.

EEA, UK and Switzerland (GDPR): you have the rights of access, rectification, erasure, restriction, portability, objection, and to withdraw consent at any time. For the analytics and crash data we cannot identify you, so access, rectification, erasure and portability cannot be fulfilled for it (GDPR Article 11); you can still withdraw ad consent (in iOS Settings, or in the App on Android), stop all processing by uninstalling, and exercise rights over advertising data through Unity (https://unity.com/legal/game-player-and-app-user-privacy-policy) or Meta (https://www.facebook.com/privacy/policy/). You may lodge a complaint with your data protection authority (EU list: https://www.edpb.europa.eu/about-edpb/about-edpb/members_en; UK: https://ico.org.uk; Switzerland: https://www.edoeb.admin.ch). We would appreciate the chance to help first.

California: we do not sell personal information. If passing the advertising identifier to Unity or Meta for personalized ads counts as “sharing”, you can opt out by not allowing tracking on iOS; on Android by choosing “Non-personalized ads” (for Unity) and deleting your advertising ID or opting out in your device’s ad settings, for example Settings > Google > Ads (for Meta); by buying Premium; or by uninstalling the App. You may also ask to know, correct or delete personal information and will not be discriminated against for asking; the same identification limit applies. Contact us by e-mail.

Children

The App is not directed to children under 13 (16 in the EEA), and we do not knowingly collect personal information from children. If you are a parent or guardian and are concerned, uninstall the App; no individual record exists that we could look up or delete.

Premium

Premium is a one-time, non-consumable purchase: no subscription, no trial, no recurring charge. It removes ads and unlocks example audio and word management for all groups. Your premium status is stored on your device and verified with the store; if the store cannot confirm it (for example offline), Premium is kept for a 7-day grace period. “Restore Purchases” in Settings recognizes a purchase made on another device or before a reinstall.

Security

Data sent to Google, Unity and Meta travels over HTTPS/TLS. On-device data is protected by your device’s own security.

About this policy

This page describes what happens when you use the App; it is not a request for consent, and using the App is not treated as consent. Where consent is needed (personalized ads, asked of everyone using the free version; tracking on iOS), the App asks you separately and you can withdraw at any time. We may update this page; the date at the top changes when we do.

Change history

October 2, 2026: ProVocab is now also available on Google Play. On Android, ads come from the same networks as on iOS (Unity Ads, ironSource Ads and Meta Audience Network, through Unity LevelPlay). The App’s consent sheet now names Meta; your answer reaches Unity, while Meta follows your device’s ad settings. On Android, Meta Audience Network does not serve ads in the EEA, the UK and Switzerland. Copies on Google Play’s pre-launch test devices or installed from outside the Play Store show no ads. Nothing else changed about what is collected.
September 29, 2026: Meta Audience Network (operated by Meta) can now fill ad requests in the free version, through Unity LevelPlay. On iOS it follows your tracking permission, like Unity. Recipients, retention and transfers updated. Nothing else changed about what is collected.
September 26, 2026: On iOS the tracking prompt is now the ad-consent question, preceded by an information screen with a “Continue” button; change it in the iOS Settings app. Android is unchanged. Nothing changed about what is collected.
September 24, 2026: Ads are now served by Unity’s networks Unity Ads and ironSource Ads (mediated by Unity LevelPlay) instead of Google AdMob. The ad-consent question is asked by the App itself, to every user of the free version, before the first ad; the iOS tracking prompt appears only if you choose personalized ads. Recipients, retention and transfers updated for Unity. Nothing else changed about what is collected.
September 19, 2026: Added the Study Calendar. Opening it sends one analytics event with the number of days you have studied. Nothing else changed about what is collected.
September 8, 2026: The purchase event sent to Firebase Analytics now includes the store’s transaction number, and is sent only once per purchase. It previously could be sent twice for a single purchase, which double-counted it. Nothing else changed about what is collected.
September 5, 2026: Rewritten in plain language and re-checked against the app. Corrections: no deletion-on-request claim; IP-based approximate location applies to all users; Premium is a one-time purchase, not a subscription; the analytics identifier is the Firebase installation ID plus the iOS IDFV; the list of usage data now matches what the app actually sends (language preferences, screens viewed, learned-word and audio actions removed; review results, streaks, purchase price, ad outcomes added); the ad consent form and “Ad Privacy Settings”, the iOS tracking prompt, daily reminders, backup export/import, system backups and Google Fonts downloads are described; legal bases, complaint right, controller and transfer details added; the “use = consent” clause and the in-app-notice promise removed
January 24, 2026: First version
