Privacy Policy

Effective date: 21st February, 2026

This Privacy Policy explains how Lemonomics FlexCo (“Lemonomics,” “we,” “us”) collects, uses, shares, and protects personal information when you use:

• the Lemonomics mobile app (iOS and Android) (the “App”), and

• our website and related pages (the “Site”), including landing pages and legal/help pages.

If you do not agree with this Privacy Policy, please do not use the App or the Site.

1) Who we are (Controller) and how to contact us

Controller: Lemonomics FlexCo
Address: Passinigasse 40, 1100 Vienna, Austria
Email: support@lemonomics.app

If you contact us, we may ask you for information to verify your identity before we respond.

2) What information we collect

We collect information in three ways: (A) information you provide, (B) information collected automatically, and (C) information from third parties.

A) Information you provide

Account and profile information

• First name and last name

• Email address

• Age (you must be at least 13 to use Lemonomics)

• Password (if you sign up with email/password)

• Sign-in method (e.g., Apple / Google)

Learning and in-app activity

• Your lesson progress (e.g., units/lessons completed)

• Your answers and attempts (e.g., quiz responses)

• Streak and engagement-related data (where applicable)

Communications

• Information you provide when you contact support (e.g., messages and attachments you choose to send)

• Feedback, survey responses, and feature requests

B) Information we collect automatically

Device, app, and usage information

• Device type, operating system, app version, language settings

• App interactions and usage analytics (e.g., screens viewed, session duration, feature usage)

• Crash reports and performance data

Identifiers and technical data

• IP address and approximate location derived from IP (general region)

• Device identifiers and advertising identifiers (where available), such as IDFA/AAID

Website cookies and similar technologies (Site)

• Cookies and similar technologies used to operate the Site, remember preferences, measure performance, and support marketing/retargeting (details in Section 6).

C) Information from third parties

Sign-in providers

• If you sign in using Apple or Google, we receive certain information from them (such as a stable account identifier and, depending on your settings, your email address).

App stores and subscription providers

• When you purchase a subscription through Apple App Store or Google Play, the payment is processed by Apple/Google.

• We receive subscription status/entitlement information (e.g., active subscription, trial status) and may receive transaction identifiers needed to manage access.

Advertising, measurement, and analytics partners

• We use third-party SDKs and services for analytics, attribution, and advertising measurement.

• These partners may provide us with aggregated reports and/or event-level data tied to device identifiers.

3) What we do not collect (and what we ask you not to send)

• We do not intentionally collect sensitive personal data (such as health information, biometric data, precise geolocation, or government IDs) as part of the normal operation of Lemonomics.

• We do not ask for (and generally do not need) access to your contacts, photos, camera, or microphone to provide the core learning experience.

Please do not send sensitive information in support messages. If you voluntarily include it, we may process it only to respond to you and provide support.

4) How we use your information

We use personal information to:

1. Provide and operate the App and Site (create accounts, deliver lessons, maintain functionality).

2. Personalize and improve learning (e.g., saving progress, adapting lesson flow).

3. Analytics and product improvement (understand what works, fix bugs, improve usability and learning outcomes).

4. Security and fraud prevention (protect users, enforce policies, prevent abuse).

5. Communicate with you (support responses, service announcements, account notices).

6. Marketing and growth

7. Show Lemonomics ads on third-party platforms (retargeting) and measure campaign effectiveness.

8. Send push notifications and, if enabled in the future, emails (you can opt out of marketing communications).

We may also create and use aggregated or de-identified data (data that does not reasonably identify you). We may use this for analytics, research, and improving Lemonomics.

5) Legal bases (EEA/UK users)

If you are in the EEA/UK/Switzerland, we process your personal information under these legal bases:

• Contract: to provide the App/Site and features you request (e.g., account creation, progress tracking).

• Legitimate interests: to improve the App, understand usage, ensure security, and grow our business (balanced against your rights).

• Consent: where required (e.g., certain cookies on the Site, marketing preferences where applicable).

• Legal obligations: where we must comply with applicable laws (e.g., accounting/tax, responding to lawful requests).

6) Cookies and similar technologies (Site)

We use cookies and similar technologies on the Site to:

• Operate the Site (necessary cookies)

• Remember preferences (e.g., language settings)

• Measure performance and understand Site usage (analytics cookies)

• Support marketing and retargeting (marketing cookies), where permitted

Cookie choices and Cookiebot

We use a consent tool (such as Cookiebot) to help you manage cookies on the Site.

• You can accept or refuse non-essential cookies through the cookie banner or by updating your preferences.

• If you disable certain cookies, parts of the Site may not function properly.

Global Privacy Control (GPC)

Some browsers support the Global Privacy Control signal. Where required by applicable law and where technically feasible, we will treat a valid GPC signal as a request to opt out of certain marketing cookies/retargeting on the Site.

7) Advertising and retargeting

In-app ads

Lemonomics may show ads in the free version of the App.

• We intend to show non-personalized ads (also called “contextual” ads), meaning ads are not selected based on a profile of your behavior across apps and websites.

• Even with non-personalized ads, ad networks may process device identifiers and technical data to:

• deliver ads,

• cap frequency,

• detect and prevent fraud,

• measure performance and generate reporting.

Retargeting (ads outside the App)

We may run retargeting campaigns on third-party platforms (for example, Google) so people who visited our Site or interacted with our ads may see Lemonomics ads later.

• Retargeting typically uses cookies (on the Site) or device identifiers (on mobile) to measure and re-engage audiences.

• This may involve sharing or making available certain identifiers to advertising partners.

Your advertising choices

• Site cookies: Use the cookie banner/preferences tool on our Site to manage non-essential cookies used for marketing/retargeting.

• Device ad settings: You can also limit ad tracking through your device settings (iOS/Android).

• Contact us: You can request help opting out of certain marketing/retargeting activities by emailing support@lemonomics.app.

“Sale” / “sharing” under some U.S. laws

Under some U.S. state privacy laws, sharing identifiers for cross-context advertising may be considered “sharing” or a “sale” of personal information, even if no money is exchanged. See Section 12 for additional U.S. disclosures and opt-out rights.

8) How we share information

We share personal information only as described below.

A) Service providers (processors)

We use trusted vendors to help run the App and Site. Depending on your use, these may include:

• Hosting / infrastructure: Google Cloud Platform (and related services)

• Database / storage: MongoDB (e.g., MongoDB Atlas), Redis (caching)

• Analytics: Firebase / Google Analytics

• Attribution / measurement: AppsFlyer

• Subscriptions: RevenueCat

• Advertising: Google AdMob

• Cookie consent (Site): Cookiebot

These providers process information on our behalf and under contractual restrictions.

B) App stores and payment processors

Apple App Store and Google Play process payments and manage subscriptions under their own terms and privacy policies.

C) Legal and safety reasons

We may disclose information if we believe in good faith that it is necessary to:

• comply with applicable law or legal process,

• protect rights, safety, and security of users or the public,

• investigate fraud, abuse, or policy violations.

D) Business transfers

If we are involved in a merger, acquisition, financing, reorganization, bankruptcy, or sale of assets, information may be transferred as part of that transaction (subject to appropriate protections).

9) International transfers

We are based in Austria, but our service providers may process data in other countries (including the United States) where they or their sub-processors operate.

Where required by law, we use appropriate safeguards for international transfers, such as Standard Contractual Clauses and other lawful mechanisms.

10) Data retention and deletion

We keep personal information only for as long as necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.

Typical retention (high-level)

• Account and learning progress: retained while your account is active.

• Support communications: retained as needed to respond to you and improve support (often for a limited period).

• Analytics, measurement, and technical logs: retained for limited periods to maintain and improve the service.

• Backups: may persist briefly before being overwritten.

Account deletion

If you delete your account (or ask us to delete it):

• We will remove your user profile and learning progress from our active systems.

• We will also delete or anonymize associated data unless we need to keep certain information for legitimate purposes.

What we may retain

Even after account deletion, some information may be retained for limited purposes, such as:

• Subscription and billing records (primarily held by Apple/Google and/or reflected in entitlement logs)

• Legal compliance (e.g., accounting/tax obligations)

• Security, fraud prevention, and dispute resolution

Backups

Copies of certain data may persist in backups and logs for a limited period (typically up to ~7 days) before being overwritten or deleted.

11) Your rights and choices

Depending on where you live, you may have rights to:

• Access your personal information

• Correct inaccurate information

• Delete your information

• Object to or restrict certain processing

• Port your information (receive a copy)

• Withdraw consent where processing is based on consent

How to exercise your rights

Email support@lemonomics.app with your request. We may need to verify your identity. We aim to respond within applicable legal timeframes.

Complaints (EEA/UK)

You may lodge a complaint with your local data protection authority. In Austria, this is:

Österreichische Datenschutzbehörde (DSB)

12) Additional disclosures for certain U.S. states

This section provides additional information for residents of certain U.S. states (including California) where required by law.

Categories of personal information collected

Depending on how you use Lemonomics, we may collect the following categories (as described in Section 2):

• Identifiers: name, email address, device identifiers, advertising identifiers, IP address

• Internet or network activity: interactions with the App/Site, usage analytics

• Commercial information: subscription status and purchase-related identifiers

• Geolocation data: approximate location derived from IP

• Inferences: limited inferences from usage (e.g., likely features you prefer), primarily for product improvement

Purposes

We collect and use these categories for the purposes described in Section 4 (operation, personalization, analytics/product improvement, security, communications, marketing/retargeting).

“Sale” / “sharing” and opt-out

We do not sell personal information for money. However, as described in Section 7, we may share identifiers with advertising partners for cross-context advertising/retargeting, which may be considered a “sale” or “sharing” under some state laws.

To opt out, you can:

• adjust Site cookie preferences (marketing cookies), and/or

• email support@lemonomics.app with the subject line “Do Not Sell/Share”.

Sensitive personal information

We do not use or disclose sensitive personal information for purposes that require an opt-out right (as defined by certain laws). If we ever need to, we will provide appropriate notice and choices.

Non-discrimination

We will not discriminate against you for exercising your privacy rights.

Appeals

Where required by law, you may appeal a decision regarding your privacy request by replying to our response email and stating that you would like to appeal.

13) Children’s privacy

Lemonomics is not intended for children under 13. We do not knowingly collect personal information from children under 13.

If you believe a child under 13 has provided personal information to us, please contact support@lemonomics.app and we will take steps to delete it.

International note: If the law in your country requires a higher minimum age to consent to personal data processing, you must meet that higher age to use Lemonomics (or have a parent/guardian provide consent where required).

14) Security

We use reasonable administrative, technical, and organizational measures designed to protect personal information. However, no system can be 100% secure.

15) Changes to this Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we will take reasonable steps to notify you (for example, by posting an updated version and changing the “Effective date,” and/or via an in-app notice).
