Types of Data Collected

Personal Data

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:

• Email address
• Name
• Profile photo (when authorized)

Account and Authentication Data

Zephy allows You to create an account and sign in using third-party identity providers:

• Google Sign-In
• Apple Sign-In
• Facebook Login (Meta)

Where a feature does not require an account, You may use Zephy without signing in. Features that rely on cloud synchronization or a personal profile require authentication.

During authentication, and subject to the permissions You grant, We may receive Your name, email address and profile photo (when authorized). With Apple Sign-In, You may choose to hide Your email address, in which case We receive a private relay address instead. This information is used exclusively for authentication, account management and personalization of Your experience. It is never used for advertising and is never published to any social network.

Usage Data

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 and other diagnostic data.

When You access the Service by or through a mobile device, We may collect certain information automatically, including, but not limited to, the type of mobile device You use, Your mobile device's unique ID, the IP address of Your mobile device, Your mobile operating system, the type of mobile Internet browser You use, unique device identifiers and other diagnostic data.

We may also collect information that Your browser sends whenever You visit Our Service or when You access the Service by or through a mobile device.

Location Information

Zephy requires access to your device's location in order to provide its core functionality.

When you grant permission, Zephy may access your precise or approximate location while the application is in use.

Your location is used exclusively to:

• Display your current position on the map;
• Find nearby flying sites;
• Retrieve localized weather conditions;
• Calculate flight recommendations and safe flying windows;
• Record and display flight tracks;
• Improve navigation and flight-related features.

Zephy does not sell, rent, or share your location with third parties for advertising purposes.

Location data is only accessed after you explicitly grant permission and only while required for the application's features.

Flight Data

To provide its core flight-logging and instrument features, Zephy records data from Your device's GPS and motion sensors, including:

• GPS position (latitude and longitude);
• Altitude and height above ground level (AGL);
• Speed and direction/heading;
• Date, time, flight duration and distance traveled;
• Tracklog (the recorded path of Your flight);
• Data used to render the 3D Replay.

Flight Data is used to build Your flight history, generate the 3D Replay, calculate flight statistics, enable sharing that You explicitly initiate, and power the instrument, navigation and safety features of the Application. Flight Data is stored on Your device and, when You enable cloud sync or backup, is also stored in the cloud so You can restore it or access it across devices.

Weather Data

Zephy queries third-party meteorological services to provide localized weather information, such as wind speed and direction, temperature, atmospheric pressure and general atmospheric conditions. To retrieve relevant conditions, Your approximate or precise location may be sent to the weather provider. This data is used only to improve Your experience — for example, to display current conditions, recommend safe flying windows and support flight planning — and is not used for advertising.

Why We Collect This Data

We use collected information to:

• Provide flight planning features;
• Display weather forecasts;
• Recommend flying windows;
• Improve application performance;
• Fix bugs;
• Synchronize user information across devices;
• Enhance user experience.

Use of Your Personal Data

The Company may use Personal Data for the following purposes:

• To provide and maintain our Service, including to monitor the usage of our Service.

• To manage Your Account: to manage Your registration as a user of the Service. The Personal Data You provide can give You access to different functionalities of the Service that are available to You as a registered user.

• For the performance of a contract: the development, compliance and undertaking of the purchase contract for the products, items or services You have purchased or of any other contract with Us through the Service.

• To contact You: To contact You by email, telephone calls, SMS, or other equivalent forms of electronic communication, such as a mobile application's push notifications regarding updates or informative communications related to the functionalities, products or contracted services, including the security updates, when necessary or reasonable for their implementation.

• To provide You with news, special offers, and general information about other goods, services and events which We offer that are similar to those that you have already purchased or inquired about unless You have opted not to receive such information.

• To manage Your requests: To attend and manage Your requests to Us.

• For business transfers: We may use Your Personal Data to evaluate or conduct a merger, divestiture, restructuring, reorganization, dissolution, or other sale or transfer of some or all of Our assets, whether as a going concern or as part of bankruptcy, liquidation, or similar proceeding, in which Personal Data held by Us about our Service users is among the assets transferred.

• For other purposes: We may use Your information for other purposes, such as data analysis, identifying usage trends, determining the effectiveness of our promotional campaigns and to evaluate and improve our Service, products, services, marketing and your experience.

We may share Your Personal Data in the following situations:

• With Service Providers: We may share Your Personal Data with Service Providers to monitor and analyze the use of our Service, to contact You.
• For business transfers: We may share or transfer Your Personal Data in connection with, or during negotiations of, any merger, sale of Company assets, financing, or acquisition of all or a portion of Our business to another company.

Affiliates include Our parent company and any other subsidiaries, joint venture partners or other companies that We control or that are under common control with Us.
• With business partners: We may share Your Personal Data with Our business partners to offer You certain products, services or promotions.

• With Your consent: We may disclose Your Personal Data for any other purpose with Your consent.

Data Sharing

Zephy does not sell personal information.

Information may be shared only with trusted service providers necessary for operating the application, such as:

• Firebase Analytics
• Firebase Crashlytics
• Weather data providers
• Map service providers

These providers process information solely for delivering the requested services.

Third-Party Services

We rely on a limited set of trusted third-party providers to operate the Service. Each provider processes information only as needed to deliver its service and maintains its own privacy policy:

• Google Sign-In — authentication;
• Apple Sign-In — authentication;
• Facebook Login (Meta) — authentication;
• Google Firebase (Analytics, Crashlytics, cloud services) — analytics, crash reporting, backup and synchronization;
• Weather data provider (e.g. Open-Meteo) — weather and atmospheric conditions;
• Map / tile providers — map display and navigation.

We encourage You to review the privacy policies of these providers to understand how they handle Your information.

Facebook Login (Meta)

When You choose to sign in with Facebook Login, Zephy accesses only the information You explicitly authorize through Meta's permission dialog, which may include Your name, email address and profile photo. This data is used exclusively for authentication and for the operation of the Application. Zephy does not post, publish or share any content to Facebook or any other social network without Your explicit action and consent. You can revoke Zephy's access at any time through Your Facebook account settings (Settings & Privacy → Settings → Apps and Websites).

Social Sharing

Zephy lets You share your flying achievements with others. When You choose to share, You may share Your 3D Replay, photos, videos, flight statistics and achievements to platforms such as Facebook and Instagram, among others. All sharing is initiated by You and requires Your authorization. Zephy never publishes anything automatically or without Your explicit consent. When You share to a third-party platform, that platform's own privacy policy governs the content once it leaves the Application.

Data We Store

Depending on the features You use, Zephy may store the following:

• Account and profile information;
• Preferences and application settings;
• Flight history and tracklogs;
• Flight statistics;
• Equipment/aircraft profiles and saved routes;
• Data synchronized to the cloud (when backup or sync is enabled).

Where a feature runs entirely on Your device (for example, on-device flight intelligence and predictive analytics), that processing occurs locally and the underlying data is not transmitted to Us.

Device Permissions

Zephy requests only the permissions needed for its features. You can grant or revoke them in Your device settings.

• Location: required to record Your flight track, generate replays, and calculate speed, distance, altitude and height above ground. Foreground and, where enabled, background location are used so recording continues during flight even when the screen is off.
• Internet: required for authentication (login), cloud synchronization, backup and retrieving weather data.
• Notifications: used to deliver alerts and application features, such as safety reminders and status notifications.
• Microphone: requested only if You use features that record audio (for example, recording a video with sound), and used solely for that purpose while the feature is active.
• Storage / Media: used to save and read replays, images, videos and exported files (for example, flight track exports and shared media).

Cookies and Similar Technologies

Zephy is a mobile application and does not rely on browser cookies for its core operation. However, authentication providers and analytics tools may use tokens, device identifiers and similar technologies to keep You signed in, secure the session and measure app usage. These technologies are used only to operate and improve the Service.

Retention of Your Personal Data

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 (for example, if We are required to retain Your data to comply with applicable laws), resolve disputes, and enforce our legal agreements and policies.

Where possible, We apply shorter retention periods and/or reduce identifiability by deleting, aggregating, or anonymizing data. Unless otherwise stated, the retention periods below are maximum periods ("up to") and We may delete or anonymize data sooner when it is no longer needed for the relevant purpose. We apply different retention periods to different categories of Personal Data based on the purpose of processing and legal obligations:

• Account Information

  • User Accounts: retained for the duration of your account relationship plus up to 24 months after account closure to handle any post-termination issues or resolve disputes.

• Customer Support Data

  • Support tickets and correspondence: up to 24 months from the date of ticket closure to resolve follow-up inquiries, track service quality, and defend against potential legal claims

• Usage Data

  • Application usage statistics: up to 24 months to understand feature adoption and service improvements.
  • Server logs (IP addresses, access times): up to 24 months for security monitoring and troubleshooting purposes.

Usage Data is retained in accordance with the retention periods described above, and may be retained longer only where necessary for security, fraud prevention, or legal compliance.

We may retain Personal Data beyond the periods stated above for different reasons:

• Legal obligation: We are required by law to retain specific data (e.g., financial records for tax authorities).
• Legal claims: Data is necessary to establish, exercise, or defend legal claims.
• Your explicit request: You ask Us to retain specific information.
• Technical limitations: Data exists in backup systems that are scheduled for routine deletion.

You may request information about how long We will retain Your Personal Data by contacting Us.

When retention periods expire, We securely delete or anonymize Personal Data according to the following procedures:

• Deletion: Personal Data is removed from Our systems and no longer actively processed.
• Backup retention: Residual copies may remain in encrypted backups for a limited period consistent with our backup retention schedule and are not restored except where necessary for security, disaster recovery, or legal compliance.
• Anonymization: In some cases, We convert Personal Data into anonymous statistical data that cannot be linked back to You. This anonymized data may be retained indefinitely for research and analytics.

Summary

Personal information is retained only for as long as necessary to provide the application's services or comply with legal obligations. Users may request deletion of their account and associated data at any time.

Transfer of Your Personal Data

Your information, including Personal Data, is processed at the Company's operating offices and in any other places where the parties involved in the processing are located. It means that this information may be transferred to — and maintained on — computers located outside of Your state, province, country or other governmental jurisdiction where the data protection laws may differ from those from Your jurisdiction.

Where required by applicable law, We will ensure that international transfers of Your Personal Data are subject to appropriate safeguards and supplementary measures where appropriate. The Company will take all steps reasonably necessary to ensure that Your data is treated securely and in accordance with this Privacy Policy and no transfer of Your Personal Data will take place to an organization or a country unless there are adequate controls in place including the security of Your data and other personal information.

You may update, amend, or delete Your information at any time by signing in to Your Account, if you have one, and visiting the account settings section that allows you to manage Your personal information. You may also contact Us to request access to, correct, or delete any Personal Data that You have provided to Us.

Please note, however, that We may need to retain certain information when we have a legal obligation or lawful basis to do so.

You may request deletion of Your account and associated Personal Data in the following ways:

Children's Privacy

Our Service does not address anyone under the age of 16. We do not knowingly collect personally identifiable information from anyone under the age of 16.

Links to Other Websites

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.
