Gemini’s Built-In Safety Protections
To address Gemini privacy concerns, let’s start by reviewing the Gemini AI safety protections built into Google’s tool.
Google’s AI Safety Strategy
Google uses what’s called Automated Red Teaming (ART) for internal penetration testing of its products. Established over a decade ago, this is a dedicated team of hackers that use various techniques such as prompt injection attacks and adversarial examples to expose potential vulnerabilities.
Additionally, Google uses a network of collaborators in the Bug Bounty program to identify AI product weaknesses along with around-the-clock monitoring by its safety and security teams.
Gemini API Safety Guidance
To assist developers using the Gemini API, Google provides adjustable content filters and safety levels. The filters currently cover five categories: harassment, hate speech, sexually explicit, dangerous, and civic integrity with safety levels as high, medium, low, or negligible.
This model allows developers to adjust the settings appropriate for their application and for each request made to the API.
Filter Settings in Vertex AI
Because the Gemini API in Vertex AI can produce harmful responses based on certain prompts, developers can adjust the content filters to block potentially unsafe or damaging responses.
The system provides two “harm block” techniques for Severity and Probability and a handful of thresholds for those methods. These apply to the categories listed above providing configurable filters for inappropriate content.
Gemini App Policy Guidelines
Regarding the Gemini app, the policy guidelines address outputs that may cause real-life damage. This includes restricted responses and harm prevention rules including threats to child safety, violence, harassment, discrimination, and sexually explicit content.
Where Gemini Still Has Risks
Even with safety protections, Google Gemini isn’t infallible. If you’re getting ready to try it or are in the midst of using it, be sure that you understand the following Gemini AI risks.
📌 Hallucinations: False responses or misleading information, especially in specialized fields. For instance, a study published in 2024 by Cornell University regarding LLMs and Gemini in the healthcare industry found that “Gemini is highly susceptible to hallucinations, overconfidence, and knowledge gaps.”
📌 Prompt injection: Hidden instructions tricking the model into misbehaving. Cyber attackers can insert malicious commands to bypass safety guidelines, reveal confidential data, or uncover a system’s operation details.
📌 Bias and fairness: Moderation inconsistencies and skewed outputs. Another study published by Cornell University, this time in 2025, compared Gemini and ChatGPT in regard to gender and content bias. It found that although Gemini appeared to reduce gender bias, “this reduction comes at the cost of permitting more violent content toward both males and females, potentially normalizing violence rather than mitigating harm.”
📌 Privacy and data safety: Dangers of revealing sensitive or personal data through prompts. Data exposure, cyberattacks, data breaches, and other unauthorized actions can introduce possible safety risks and user manipulation. Additionally, human reviewers who use data to improve the product may have access to these details, especially in the free version of Gemini.
📌 External criticisms: Per an article on TechCrunch, Gemini was labeled “high-risk” for kids and teens after Common Sense Media (non-profit child safety organization) performed a risk assessment. It found that the child-based tiers produced adult versions of responses with only minor safety adjustments and thus Gemini could still provide “inappropriate and unsafe” content to children.
📌 Regulatory pressure: U.K. lawmakers accuse Google of backtracking on safety pledges. The claim, published on Time, states that when Gemini 2.5 Pro was released, Google “neglected to publish detailed information on safety tests for over a month.” This is seen as a violation of international safety commitments and also endangers the promotion of safe AI development.
How Safe Is Gemini AI in Practice?
Overall, Gemini is safe for general, low-risk queries like requesting summaries, performing casual research, and writing drafts. For example, it’s typically safe to prompt Gemini for instructions on starting an herb garden or summarizing a video on changing a tire.
Inherent danger comes in when using Gemini for sensitive, personal, or confidential tasks. For instance, you should steer clear of prompting Gemini to summarize your health records or analyze your financial statements.

User Strategies for Safer Gemini Use
To help you use the tool safely and protect yourself from risks, consider these Google Gemini safety strategies.
- Verify critical facts with reliable sources; don’t treat Gemini as an absolute authority.
- Avoid entering confidential or personal data in prompts.
- Use Gemini’s safety settings where available.
- Limit Gemini’s permissions for integrated apps.
📌 Additionally, if you’re experimenting with Gemini in Gmail or handling sensitive inbox data, be cautious not to accidentally expose private emails to the AI prompts. With privacy-focused tools like Clean Email that work alongside Gmail, you can have safer control over message content. Clean Email is available on macOS, iOS, Android, and the web, giving you secure inbox management on any device.
Screener isolates emails from unknown senders until you review and either Approve or Block them. This can reduce exposure to AI-generated spam.


Unsubscriber clears out newsletters and promotional messages. You can unsubscribe from emails in bulk and delete all previous messages from the sender, lowering the influx of suspicious emails.


Auto Clean rules automatically organize incoming emails or move those with sensitive data. This can eliminate the risk of accidentally sharing them with Gemini.

Conclusion
Gemini is safer than many other AI models thanks to Google’s protections for Gemini AI safety. But keep in mind, no AI is risk-free — hallucinations, bias, and privacy concerns continue to make users weary. Heed the cautions and apply the usage strategies to create a safe Gemini AI experience.
And for Gmail, you can combine Gemini’s protections with smart habits and inbox management tools like Clean Email to minimize risk and exposure.
