Developers: Beware of Ad Libraries that Betray Your Users’ Location

Advertising companies provide software development kits (SDKs) for mobile app monetization, which often automatically transmit users' location data to ad systems and location data brokers, raising privacy concerns. Many developers and users may be unaware of this data sharing. When developers allow SDKs to collect location data, it poses risks beyond targeted ads, including potential misuse by agencies like ICE and global surveillance. Location data brokers harvest precise movements of individuals, often without their consent, through mobile applications. Some apps directly collaborate with data brokers, while others leak data through advertising SDKs during real-time bidding (RTB) auctions. An incident in 2025 revealed that many apps unknowingly contributed to a location data broker's database. Developers must understand their SDKs' location-sharing practices to mitigate risks. Advertising SDKs can collect location data automatically once users grant permission, without specific permissions for the SDKs themselves. Precise location data can be collected when apps have location permissions, leading to potential privacy violations. Several SDKs have been identified as collecting location data by default, increasing the risk of unintentional data leaks. The Electronic Frontier Foundation (EFF) found that four advertising SDKs collect users' location data by default when location permissions are granted. InMobi encourages location sharing for higher revenue, while BidMachine updated its documentation after EFF's inquiry, confirming precise location data collection. Verve's SDK also collects location data by default but presents a cautious narrative in its Play Store guidance. Huawei's SDK recommends obtaining location permissions to enhance revenue, with default location sharing occurring if permissions are granted. Location data can be shared without users' knowledge or meaningful consent, complicating informed consent issues. The focus on four SDKs does not imply that others adequately protect location data, as many have faced criticism for similar practices. Studies indicate that SDKs often encourage increased data collection through design and documentation, leading to minimal control for developers over data transmission. The EFF's analysis highlights that advertising SDKs incentivize location data sharing through default settings and unclear documentation. Developers should assess third-party SDKs and disable unnecessary data collection. Regulators must hold developers accountable for unlawful data sharing, while legislators should enact laws to protect location privacy and address online behavioral advertising, which drives data tracking.

Binance’s Android app privacy fight is back in the spotlight

Binance is facing scrutiny regarding the data collection practices of its Android app, which some users believe functions more as a data collection tool than a trading platform. Concerns have been raised about the app's extensive permissions and tracking capabilities, with a report indicating the presence of numerous tracking components, including SDKs from TikTok and WeChat, and over 50 system permissions. Binance's privacy portal states that data is collected for account management, security, marketing, fraud prevention, and legal compliance. Despite this, there are questions about whether the data collection practices are proportionate to the app's intended functions. Binance has a history of legal issues, including a guilty plea in November 2023 that resulted in a .32 billion penalty for anti-money laundering violations. The exchange claims to tailor its privacy framework to regional regulations, but user concerns about the app's tracking capabilities persist. As of early 2026, Binance has over 300 million registered users, making any privacy-related disputes potentially impactful. The ongoing scrutiny may lead to gradual adjustments in Binance's practices rather than a complete overhaul.

Free Antivirus for Android: Best Apps to Protect Your Smartphone

Smartphones are integral to daily life, storing emails, banking apps, and social media. The Android operating system is vulnerable to threats like viruses and ransomware. Free Android antivirus tools offer basic protection but have limitations compared to paid versions. Free antivirus solutions focus on malware scanning and threat detection. Bitdefender Mobile Security (Free Version) provides lightweight background operation, real-time scanning, and web protection but lacks anti-theft and VPN features. Norton Mobile Security (Free Tier) offers essential malware scanning, with advanced features available in premium subscriptions. Avast Mobile Security (Free) includes virus scanning, malware protection, and anti-theft tools, allowing users to lock apps and protect against malicious websites. AVG AntiVirus (Free) offers virus, malware, and spyware scanning, real-time updates, and a "Photo Vault" for securing images. Kaspersky Mobile Security (Free) provides basic virus protection and ranks high in malware detection, with additional features available in paid plans. Free antivirus tools detect malware and monitor real-time system activity, alerting users to phishing sites. They may scan files transferred via USB or Bluetooth and offer limited VPN services. Limitations of free antivirus include the absence of advanced features like unlimited VPN, application locking, and anti-theft capabilities. Many rely on ads for revenue, which can disrupt user experience. Choosing the right antivirus depends on usage habits and security concerns. Running multiple antivirus apps can cause conflicts and hinder performance. Upgrading to premium versions may be necessary for comprehensive protection, especially for sensitive tasks. User behavior is crucial for security; regularly updating the OS and applications, using strong passwords, and considering two-factor authentication can enhance protection. Free antivirus apps offer core threat protection but lack advanced features. Most are lightweight, with minimal impact on performance. Regular scans are recommended, and reputable sources should be used for downloads. Free antivirus apps can warn about phishing attempts but cannot eliminate the risk entirely. A built-in VPN is not essential for basic protection but is advisable for public Wi-Fi use.

Avast Antivirus in 2026: Still Worth Paying For on Windows and Mac?

Ransomware is evolving, and many users in the United States continue to invest in Avast Antivirus as of 2026. Avast, now part of Gen Digital, has shifted from a traditional free antivirus to a comprehensive consumer security suite, which includes three tiers: Avast Free Antivirus, Avast Premium Security, and Avast One. The product lineup features a core antivirus engine, ransomware and phishing protection, a firewall, Wi-Fi inspector, built-in VPN, and performance cleanup tools. Avast's core antivirus engine provides real-time file scanning and web/email shields, consistently ranking high in independent lab tests for malware protection. The ransomware shield protects sensitive folders from unauthorized encryption, while the firewall and Wi-Fi inspector are available in paid tiers. The built-in VPN is designed for safer public Wi-Fi use, and performance tools aim to optimize system efficiency. Pricing for Avast products in the US varies, with a free tier supported by upsell prompts for premium features, Premium Security typically offered as an annual subscription, and Avast One marketed as a higher-value bundle. Renewal pricing often increases significantly after the first year, leading to user complaints. Microsoft Defender is now effective enough that many experts believe average users may not need third-party antivirus software, but Avast justifies its subscription by offering stronger web protection, more control over app permissions, and additional non-security features. User feedback highlights strong protection but frequent upsell prompts, performance issues on low-end machines, and concerns over past data collection practices. Avast is seen as valuable for households with mixed tech literacy, remote workers, students on older hardware, and users seeking basic privacy protections.
