Privacy Policy

This Privacy Policy explains how EtherFlyer Wallet handles information, what the application stores locally on your device, and how we treat any data that may be shared with us voluntarily. EtherFlyer is a non-custodial desktop wallet, which means all private keys, recovery phrases, balances, and transaction details remain fully under your control and are never transmitted to our servers or stored by the project.

Our goal is to provide a secure, transparent, and privacy-first experience. The wallet is designed to minimize data exposure, avoid unnecessary collection, and operate without creating profiles, tracking user behavior, or linking activity to identities. Any information processed by the app is handled locally and remains isolated from EtherFlyer’s infrastructure unless you choose to contact us directly.

By using EtherFlyer, you acknowledge that this policy describes how information is handled within the application and through any optional interactions with our support channels. If you disagree with any part of this document, you may discontinue using the wallet at any time.

EtherFlyer Wallet is designed to operate with strict minimal data handling. The application does not collect, transmit, or store any personal information, wallet data, or financial activity on our servers. Everything related to your keys, balances, and transactions remains exclusively on your device.

What EtherFlyer Does Not Collect

• private keys or recovery phrases
• wallet addresses or balances
• transaction history or activity logs
• IP addresses, device identifiers, or location data
• analytics, telemetry, usage statistics, or behavior tracking
• contact information such as email, name, or phone number

The app runs fully locally and does not communicate sensitive information to any external servers.

What EtherFlyer May Process Locally

• network metadata required to fetch blockchain data
• token lists and price feeds provided through public APIs
• temporary UI or cache data to improve performance
• optional local logs used for troubleshooting

This information never leaves your device unless you choose to share it manually, for example when contacting support.

EtherFlyer Wallet is designed to operate without collecting personal data or transmitting sensitive information to any external servers, meaning the amount of information the app uses is extremely limited and strictly tied to core functionality. All processing happens directly on your device, and no data leaves it unless you intentionally choose to share something manually. The information handled locally is used solely to allow the wallet to function — such as displaying balances, fetching public token lists, calculating fees, interpreting network conditions, and maintaining a smooth user interface.

EtherFlyer does not create user profiles, track behavior, collect analytics, gather telemetry, or monitor your activity within the application. The wallet includes no tracking scripts, marketing tools, or third-party data collectors, and it does not send background requests that would transmit personal or financial information. All blockchain-related interactions remain between your device and the respective networks, and EtherFlyer plays no custodial or intermediary role.

The only situation in which we may receive information from you is when you voluntarily choose to share it — for example, when contacting support. This may include a description of your issue, files you attach, or logs you decide to export and send. Such information is used solely for troubleshooting and resolving your request; it is not stored permanently, not analyzed for any secondary purpose, and never shared with third parties.

Although EtherFlyer does not collect personal data or transmit wallet information automatically, there are situations in which you may choose to share certain details with us. Providing this information is always voluntary, and it occurs only when you intentionally initiate communication with the EtherFlyer team — for example, when requesting help, reporting a bug, or submitting feedback.

When you contact support, you may provide information such as a written description of the issue, screenshots, or optional diagnostic logs exported from the app. These logs remain stored locally on your device until you decide to share them manually, and they contain only technical data relevant to troubleshooting — never private keys, seed phrases, wallet balances, or transaction contents. Any information you submit is used solely to diagnose and resolve the problem you contacted us about, and it is not analyzed for secondary purposes, stored for long-term retention, or combined with any external data sources.

In some cases, users may also choose to share general feedback, suggestions, or compatibility reports related to operating systems, network performance, or integration tools. This type of information helps us improve EtherFlyer, but it remains optional and entirely user-initiated. None of it is linked to personal identities or used for marketing, profiling, or analytics.

EtherFlyer never requests sensitive information such as private keys, recovery phrases, passwords, verification codes, or access credentials. If anyone contacts you claiming to represent EtherFlyer and asks for such information, you should treat it as a scam. We will never ask for anything that grants access to your wallet or funds.

EtherFlyer is built on a privacy-first architecture designed to ensure that your information stays on your device and never passes through our servers. Because the wallet does not collect personal data, private keys, or transaction histories, the surface area for data exposure is inherently minimal. Still, we apply strict security principles to safeguard any optional information you may choose to share with us and to maintain the integrity of the software itself.

All sensitive wallet operations — key generation, signing, encryption, and local storage — occur entirely within the app’s isolated environment. No private keys or seed phrases ever leave your device, and they are never transmitted, uploaded, or synced to any external service. When you export logs or send information to support, the data remains encrypted during transit and is used only for resolving the issue you report.

Security Principles We Follow

• Local-only key storage: Private keys and recovery phrases never leave the device or interact with our servers.
• End-to-end responsibility model: Only the user can access their wallet; no backdoors, recovery channels, or server-side overrides exist.
• Secure distribution: All official builds are digitally signed to prevent tampering or substitution with malicious binaries.
• Minimal external communication: The app connects only to public blockchain nodes, price feeds, and required network metadata — never to data-collection endpoints.
• Controlled optional logs: Any diagnostic logs you choose to send contain no identifying or sensitive data.

Because EtherFlyer is non-custodial and server-independent, your security largely depends on the safety of your own device. Maintaining an updated operating system, using reliable antivirus protection, and avoiding risky downloads are essential parts of keeping your wallet secure.

EtherFlyer Wallet does not share, sell, or distribute any personal data to third parties. The application is fully non-custodial and stores all sensitive information—such as private keys, balances, transaction history, or user identifiers—exclusively on your device. Because we do not collect this data, we have nothing to transmit, disclose, or make available to external parties.

We do not work with advertising networks, analytics providers, tracking services, or data brokers. EtherFlyer does not use third-party SDKs that gather behavioral information, nor does it allow any external service to access your wallet, activity, or device environment.

The only situation in which EtherFlyer may receive information is when you voluntarily choose to send it, such as when submitting logs or screenshots while requesting support. This information is used solely for troubleshooting and is never shared with any third party, partner, or external organization.

EtherFlyer may be legally required to disclose information if mandated by applicable law or court order. However, because we do not store personal data, wallet information, or user identifiers, there is no sensitive information that can be provided beyond what a user voluntarily submits.

We Never Share:

• private keys or recovery data
• wallet addresses, balances, or transaction histories
• device identifiers, IP information, or location data
• support messages or logs with external parties

EtherFlyer is a fully local, non-custodial wallet, meaning all information is stored and processed only on your device. While we do not collect or maintain user data on our servers, you still retain full control over the information the app handles locally. Your rights apply directly to the data stored on your own machine.

Your Rights as a User

• Access and Review — You may view all data available within the app at any time, including balances, transaction history pulled from public networks, locally stored settings, and optional diagnostic logs.
• Modify or Update — You may adjust preferences, change your password, manage networks, add or remove accounts, and update local configuration without restrictions.
• Delete Local Data — All data used by EtherFlyer exists only on your device. You may delete the app and its folders at any time to remove settings, cache files, or logs. (Important: deleting the app does not delete your wallet on the blockchain. You must keep your recovery phrase to access your funds.)
• Limit Local Processing — You can disable optional features—such as saving diagnostic logs or caching token lists—if you prefer to minimize what the wallet stores locally.
• Data Portability — You can export your wallet at any moment using a recovery phrase or private key and import it into any compatible application. EtherFlyer does not restrict migration.

EtherFlyer Wallet interacts with certain third-party services to display blockchain data, token information, or market insights. These services are not operated or controlled by EtherFlyer, and their behavior, data handling practices, or availability fall outside our responsibility. The wallet only retrieves publicly accessible data and does not transmit personal information, wallet details, or identifiers to external providers.

What Third-Party Services May Provide

• Public token lists and metadata
• Blockchain RPC endpoints or public nodes
• Market price feeds from open sources
• Contract information and verification data
• Optional community integrations such as analytics or dashboards

These services only provide data to the wallet; they do not receive your private keys, addresses, balances, or personal information from EtherFlyer.

Your Responsibilities When Using Third-Party Tools

You are responsible for evaluating any third-party integration you choose to enable. EtherFlyer cannot guarantee the accuracy, uptime, or security of external APIs, nor can we control how those external providers treat information accessed through their platforms.

If you interact directly with a third-party service (for example, by visiting a website, connecting to an RPC provider, or using a community-built integration), your use of that service is governed by their own terms and privacy policies.

No Endorsement or Liability

• Delays or downtime caused by an external provider
• Inaccurate or outdated information supplied by third parties
• Changes in third-party policies, endpoints, or service behavior
• User losses resulting from reliance on external data

The wallet offers these integrations solely for convenience, and all third-party usage is optional.

EtherFlyer Wallet does not use cookies, tracking scripts, analytics tools, or any form of behavioral monitoring. The desktop application operates entirely on your device and does not load remote content that could introduce third-party trackers or invisible scripts. Since all wallet activity stays local, the app has no mechanism for tracking usage, collecting identifiers, or profiling user behavior. The software does not transmit browsing data, hardware information, IP addresses, or telemetry of any kind.

The official EtherFlyer website also follows a strict no-tracking policy. We do not use advertising cookies, fingerprinting tools, session replay technologies, or cross-site identifiers. The site may use limited, short-lived technical cookies that exist only to support essential page functions, such as maintaining your selected language or ensuring stable loading of UI assets. These cookies cannot identify you and are never linked to wallet actions, blockchain addresses, or device information.

Any interaction with third-party websites, tools, or integrations linked from EtherFlyer is governed entirely by their own policies. External services may set cookies or trackers according to their terms, which operate independently from EtherFlyer. We do not embed third-party analytics, do not load external marketing libraries, and do not share any data with advertising networks. Our approach remains simple: all core functionality must work without collecting or storing personal information, and neither the app nor the website should create any form of digital trace tied to the user.

EtherFlyer Wallet follows a strict minimal-retention model. The application does not store user data on external servers, does not maintain cloud backups, and does not keep any long-term records of wallet activity. All sensitive information, such as private keys, recovery phrases, addresses, balances, and transaction history, is generated and stored locally on your device. This information remains fully under your control and is never transmitted to EtherFlyer or any third party.

Local data created by the wallet—such as configuration files, token cache, and optional logs—is stored only on your device and can be deleted at any time by uninstalling the application or clearing the app directory. EtherFlyer does not keep a remote copy of these files and cannot restore or recover them if they are removed. Because we do not operate user accounts, centralized dashboards, or cloud sync services, there is no server-side retention period and no centralized storage of user-related information.

Any information you voluntarily share with the team, such as diagnostic logs or bug reports, is kept only for as long as needed to address the issue. These files are never linked to personal identifiers and may be deleted immediately upon request. EtherFlyer does not create long-term archives of support interactions and does not store data for marketing, analytics, legal discovery, or behavioral monitoring. Once the information is no longer required for troubleshooting, it is permanently removed.

This approach ensures that your data is always in your possession. If you choose to stop using EtherFlyer, all wallet information remains on your device, and no additional action is required to erase it from our systems, since we do not retain it in the first place. Your privacy and control over your own data remain preserved at every stage of using the wallet.

EtherFlyer is designed according to internationally recognized privacy and data-protection principles, including data minimization, local-only processing, and user autonomy. While the wallet does not qualify as a custodial service and does not store or manage user assets on centralized servers, we follow widely accepted standards that guide responsible handling of technical data.

EtherFlyer’s privacy model aligns with core principles found in frameworks such as:

• GDPR — minimal data collection, no tracking, no personal identifiers, data remains fully user-controlled.
• MiCA — EtherFlyer does not fall under custody or asset-service provider definitions, but respects the transparency and user-protection values encouraged by the regulation.
• CCPA — no sale, sharing, or collection of personal information, and no profiling or behavioral tracking.
• Industry best practices for non-custodial crypto tools, including local-only key storage, offline seed handling, and zero-knowledge design principles.

Because EtherFlyer does not collect personal data, does not run centralized analytics, and does not maintain user accounts, many regulatory obligations (such as the right to data access, correction, export, deletion, or objection) are fulfilled by default — the only person who possesses the data is the user themselves.

Users remain responsible for ensuring that the use of cryptographic tools is permitted in their jurisdiction. Laws governing blockchain software vary by country, and EtherFlyer cannot determine or interpret local restrictions. The wallet is offered as a software tool, and it is the user's obligation to confirm that downloading or using such software complies with applicable laws, sanctions, and regulatory requirements in their region.

EtherFlyer may update or revise this Privacy Policy from time to time to reflect changes in the software, security practices, supported networks, or applicable legal requirements. Updated versions will be made available on the official website, and the “Last Updated” date will indicate when the revisions took effect. Because EtherFlyer does not operate accounts or collect contact information, we cannot deliver direct notifications regarding updates. You are responsible for periodically reviewing this Policy to remain informed about how your data is handled.

Continued use of EtherFlyer after an updated Privacy Policy is published constitutes acceptance of the revised terms. If you do not agree with any changes, you must discontinue use of the wallet and remove it from your device. Since EtherFlyer is non-custodial and operates entirely on your device, choosing to stop using the software does not affect your access to blockchain networks through alternative tools.

Revisions to this Privacy Policy do not apply retroactively and do not alter the security or ownership of your digital assets. Updates are made to maintain transparency, accuracy, and alignment with evolving technical and regulatory standards.
