This Privacy Policy describes Our policies and procedures on the collection, use and disclosure of Your information when You use the Service and tells You about Your privacy rights and how the law protects You.
We use Your Personal data to provide and improve the Service. By using the Service, You agree to the collection and use of information in accordance with this Privacy Policy.
The words of which the initial letter is capitalized have meanings defined under the following conditions. The following definitions shall have the same meaning regardless of whether they appear in singular or in plural.
For the purposes of this Privacy Policy:
While using Our Service, We may ask You to provide Us with certain personally identifiable information that can be used to contact or identify You. Personally identifiable information may include, but is not limited to:
Usage Data is collected automatically when using the Service.
Usage Data may include information such as Your Device's Internet Protocol address (e.g. IP address), browser type, browser version, the pages of our Service that You visit, the time and date of Your visit, the time spent on those pages, unique device identifiers, Your Advertising Identifier, and other diagnostic data. When ads are served, our advertising partners may also collect information about Your interactions with the ads.
While using Our Application, in order to provide features of Our Application, We may collect, with Your prior permission:
Our Application uses the following third-party services that may collect information used to identify you:
We use Google Firebase services — including Google Analytics for Firebase, Firebase Crashlytics, Firebase Cloud Messaging, and Firebase cloud storage — to understand how users interact with the Application, to analyze behavior, to diagnose crashes, and to improve the Service. To do this, Firebase may collect and process data such as device information, operating system, app version, unique installation and device identifiers, in-app events and screens viewed, session duration, interaction and behavioral data, approximate (non-precise) location derived from IP address, and crash diagnostics.
This behavioral and analytics data helps Us measure engagement, build aggregated audience insights, and improve features. Where required by law, We collect this analytics data only after obtaining Your consent through our Consent Management Platform, and You can withdraw Your consent at any time.
For more information about Firebase's privacy practices, please visit the Firebase Privacy and Security page and the Google Privacy Policy. You can also learn how to control Google Analytics collection.
When you choose to sign in with Google, we collect basic profile information including your name, email address, and profile picture. This information is provided by Google and is subject to Google's Privacy Policy.
When you choose to sign in with Apple, we may collect basic profile information including your name and email address (or a private relay email address). This information is provided by Apple and is subject to Apple's Privacy Policy.
We use Google AdMob to display advertisements within the Application. AdMob is an advertising service provided by Google. To serve ads, AdMob and its partners may collect and process data including Your Advertising Identifier, IP address, device information, general (non-precise) location, and information about Your interactions with the ads. This data may be used to deliver Personalized Advertising as well as to measure ad performance and prevent fraud.
For more information about how Google uses this data, please see How Google uses information from sites or apps that use our services and the Google Privacy Policy.
The Application is supported in part by advertising. Depending on Your consent and device settings, the ads You see may be personalized based on Your Advertising Identifier and app activity, or non-personalized. Where required by law, we (or our advertising partners) will ask for Your consent before serving personalized ads and rely on a consent management platform to record Your choice.
You can control or opt out of Personalized Advertising in the following ways:
If You opt out of Personalized Advertising, You may still see ads, but they will not be tailored to Your interests.
The Company may use Personal Data for the following purposes:
We may share Your personal information in the following situations:
Where required by applicable law, We use Google's User Messaging Platform (UMP) SDK as our Consent Management Platform to request Your permission before collecting analytics data or serving Personalized Advertising. This includes obtaining consent under the GDPR for users in the European Economic Area, the United Kingdom, and Switzerland, and providing the required notices and choices for users in the United States.
You may withdraw or change Your consent at any time through the Application's settings or by using the device-level controls described in the "Advertising and Your Choices" section above. Withdrawing consent does not affect the lawfulness of processing carried out before the withdrawal.
The Company will retain Your Personal Data only for as long as is necessary for the purposes set out in this Privacy Policy. We will retain and use Your Personal Data to the extent necessary to comply with our legal obligations, resolve disputes, and enforce our legal agreements and policies.
Account information is retained for as long as Your account remains active. Usage Data and analytics data are generally retained for a limited period in accordance with the retention settings of our analytics and advertising providers (for example, Google Analytics for Firebase data retention controls). Advertising-related identifiers are retained by our advertising partners according to their own policies. When Personal Data is no longer required, We will delete or anonymize it.
The security of Your Personal Data is important to Us, but remember that no method of transmission over the Internet, or method of electronic storage is 100% secure. While We strive to use commercially acceptable means to protect Your Personal Data, We cannot guarantee its absolute security.
Your information, including Personal Data, may be processed at, and transferred to, computers and servers located outside of Your state, province, country, or other governmental jurisdiction, including the United States, where data protection laws may differ from those in Your jurisdiction. Where We transfer Personal Data of users in the European Economic Area, the United Kingdom, or Switzerland to countries that have not received an adequacy decision, We (and our Service Providers, such as Google) rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses. By using the Service or providing Your consent, You acknowledge these transfers.
If You are located in the European Economic Area, the United Kingdom, or Switzerland, We process Your Personal Data on the following legal bases:
If You are located in the European Economic Area, the United Kingdom, or Switzerland, You have the following rights regarding Your Personal Data:
To exercise any of these rights, please contact Us at support@679labs.com. We will respond to Your request in accordance with applicable law.
If You are a resident of California or another U.S. state with a comprehensive privacy law (such as Virginia, Colorado, Connecticut, or Utah), You may have additional rights regarding Your Personal Data (referred to in these laws as "personal information").
In the preceding 12 months, We may have collected the following categories of personal information: identifiers (such as email address and device and advertising identifiers), internet or other electronic network activity information (such as app interaction and behavioral data), approximate geolocation derived from IP address, audio information (audio recordings You provide for language learning), and inferences drawn to create a profile about Your preferences.
"Sale" and "Sharing". Some U.S. state laws define the use of advertising identifiers for cross-context behavioral (Personalized) Advertising as a "sale" or "sharing" of personal information. To the extent Personalized Advertising through Google AdMob constitutes a "sale" or "sharing" under these laws, We provide You the right to opt out.
Subject to applicable law, You have the right to:
How to opt out (Do Not Sell or Share My Personal Information). You can opt out of the sale or sharing of Your personal information and of Personalized Advertising by declining consent in the in-app consent prompt, by using the device-level controls described in the "Advertising and Your Choices" section, or by contacting Us at support@679labs.com. We also honor recognized opt-out preference signals (such as Global Privacy Control) where required by law. You may designate an authorized agent to make a request on Your behalf.
Our Service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from anyone under the age of 13. If You are a parent or guardian and You are aware that Your child has provided Us with Personal Data, please contact Us.
Our Service may contain links to other websites that are not operated by Us. If You click on a third party link, You will be directed to that third party's site. We strongly advise You to review the Privacy Policy of every site You visit.
