Is Your AI Assistant Spying on You? How to Protect Your Privacy

Voice assistants, chatbots, and AI-powered smart devices have become nearly invisible fixtures of daily life. They set reminders, answer questions, suggest recipes, and even compose emails. The convenience is real. But the data these tools collect in the process often goes far beyond what most users realize.

Recent reporting by Heather Parry on Substack, and growing scrutiny from regulators, has drawn attention to a quiet but important shift: as AI tools become more capable, they also become more invasive. This isn’t about paranoia. It’s about understanding how everyday AI tools collect, store, and sometimes share your personal information — and what you can do to limit that exposure.

What happened

The core issue is that most consumer AI tools are built on massive data-hungry models. To improve their responses, companies collect voice recordings, text inputs, search history, device information, and sometimes even behavioral patterns from how you interact with the service. In many cases, this data is used not only to train the AI but also to personalize ads or sold to third-party data brokers.

Examples are easy to find. ChatGPT, Google Bard (now Gemini), and Amazon Alexa all require extensive permissions. For instance, to use advanced voice features on ChatGPT, you may need to enable microphone access across all apps. Google’s AI services often tie into your full search and location history by default. Amazon has been known to retain voice recordings even after you delete them, as reported in several privacy audits.

Heather Parry’s article highlights how these practices, when combined with the rapid adoption of AI, represent an erosion of privacy that many users are unaware of until it’s too late. The piece notes that the terms of service for many AI tools include clauses that allow data to be shared with subcontractors or used for unrelated purposes.

Why it matters

The consequences are not abstract. If you ask a chatbot for medical advice or help with a sensitive financial question, that input becomes part of a dataset that could be accessed by employees, auditors, or inadvertently leaked in a breach. In 2023, a bug in ChatGPT exposed users’ chat histories to other people. Similar incidents have occurred with smart speakers recording private conversations and sending them to random contacts.

Moreover, the permissions you grant to an AI app on your phone can extend beyond the app itself. Many apps request access to contacts, photos, and location even when those features aren’t strictly needed for the AI function. Once granted, that data can be used for ad targeting or sold — often in ways buried in privacy policies that few read.

The real risk is that the erosion happens slowly. You allow one permission, then another, and soon you’ve handed over a detailed profile of your life without a clear understanding of who holds the keys.

What readers can do

You don’t need to stop using AI tools entirely. But you should adjust how you use them. Here are concrete steps that limit data collection without giving up the benefits:

  1. Review and restrict permissions. On both iOS and Android, go to Settings > Apps and check what permissions each AI app has. Revoke microphone, camera, and location access if they aren’t essential. For text-based chatbots, microphone access is rarely needed.

  2. Turn off voice recording history. For Alexa, Google Assistant, and Siri, you can disable voice recording storage or set automatic deletion after a short period. Amazon and Google both have settings under Privacy that let you manage and delete recordings.

  3. Use incognito or ephemeral modes. ChatGPT offers a “temporary chat” mode (available on the web and mobile) that does not save conversations to your history or use them for training. Bard (Gemini) similarly allows you to turn off activity tracking. Enable these options before asking anything sensitive.

  4. Avoid sharing personally identifiable information. Treat AI chatbots the way you would a stranger on the internet. Don’t share your full name, address, Social Security number, or financial account details unless you are certain of the privacy protections — and even then, think twice.

  5. Choose privacy-focused alternatives. For voice assistants, consider open-source options like Mycroft or use on-device processing when available. For text AI, tools like Ollama let you run models locally on your own computer, keeping data entirely under your control. These options are less polished but avoid third-party server storage.

  6. Read the privacy policy — or at least the summary. Many apps now provide a short, readable version of their data practices. Look for phrases like “we may share with third parties” or “data used for training.” If you’re uncomfortable, use the web version of the tool in a privacy-focused browser with tracking protection enabled.
