Privacy Policy

Last updated: September 2, 2026

This Privacy Policy explains what information MemorySpark ("the app," "we," "us") collects, how it's used, and the choices you have. MemorySpark is a flashcard and language-learning app published by Idea Solutions.

Information we collect

Account information

Email address and password (if you sign up directly), or your name and email if you sign in with Google. Signing in with Apple may not include an email at all, or may include a private relay address instead of your real one — Apple only shares this at your discretion, and only on your first sign-in
A display name you choose during setup
Your base language and the language(s) you're learning

Content you create

Flashcard decks, individual cards, and any text, images, or audio you add to them
Study activity — which cards you've reviewed, when, and how well you did (used to schedule future reviews)
Saved articles and any word lists or text you import to generate cards

Purchases and subscription status

Your subscription tier (Free, Premium, or Atelier) and renewal date
Your AI-image credit balance
We do not receive or store your payment card details — purchases are handled entirely by Apple's App Store or Google Play, and our payment processor, RevenueCat, only tells us that a purchase happened and which product was bought

Information collected automatically

Device type and app version, for support and debugging
A push notification token, if you enable reminders, so we can send them
On iOS, an advertising identifier — but only if you grant permission via Apple's App Tracking Transparency prompt; if you decline, ads are shown without it

How we use your information

To run the core app — storing your decks, tracking review progress, and scheduling what to study next
To process purchases and grant the credits or access tier you paid for
To generate AI images and translations you request (see below — this involves sending your prompt/text to a third-party AI provider)
To send study reminders, if you've enabled them
To show ads to free-tier users, and to detect and prevent fraud or abuse of free trials, credits, and refunds

Third parties we share data with

We don't sell your personal information. We do share limited data with the following services, each of which processes it under their own privacy policy, to provide specific features:

Service	What it's used for	What's shared
Google Firebase	Account sign-in, database, file storage, server functions, push notifications, hosting	All account and app-content data described above
OpenAI	Generating AI images for flashcards	The text prompt you write for the image; OpenAI does not receive your account identity
Google Cloud Translate	Translating words/phrases	The text being translated
RevenueCat	Managing subscriptions and purchases across app stores	Purchase receipts and your subscription status
Google AdMob	Showing rewarded video ads to free-tier users	Advertising identifier (iOS: only with your permission), device/app info standard to mobile ad serving
Google Sign-In / Sign in with Apple	Social sign-in, if you choose it	Handled directly between your device and Google/Apple; we receive only your name and email

We may also disclose information if required by law, or to protect the rights, safety, or property of MemorySpark or our users.

Data retention and deletion

We keep your account data for as long as your account exists. You can delete your account at any time from within the app (Account settings), which permanently removes your profile, decks, cards, and study history from our systems. Some records — such as purchase receipts — may be retained separately by Apple, Google, or RevenueCat under their own retention rules, and residual copies may persist briefly in backups before being purged.

Children's privacy

MemorySpark is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we'll delete it.

Your choices

Notifications: can be turned off in your device's system settings at any time
Ad personalization (iOS): controlled by the App Tracking Transparency prompt; you can change your answer later in iOS Settings → Privacy → Tracking
Account deletion: available in-app under Account settings, or via our account deletion request page if you can't sign in
Data access or questions: contact us using the details below

International data transfers

Our service providers may process and store data in countries other than your own, including the United States. By using the app, you consent to this transfer, in accordance with this policy.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above; continued use of the app after a change means you accept the updated policy.

Questions about this policy or your data? Email us at phpdevelopmentca@gmail.com, or reach us through the app's Account screen (Contact Support), which generates an 8-digit support code. We rely on this code rather than your email to identify your account — not every account has a usable email on file (Apple sign-in doesn't always provide one), so the code is the one identifier we can count on across every sign-in method.
