Google Gemini vs GitHub Copilot

Google says it collects the information you provide, created content, device details, activity, location, cookies, and information from partners or public sources. For users, that means Gemini may sit inside a much wider Google data ecosystem than just your chatbot prompts.

Google may combine information across its services, devices, and even some third-party sites/apps using Google services. This can increase profiling and make your activity in one product influence personalization or ads elsewhere.

Your data may be used for personalized content and ads, depending on settings. Although Google says it does not share directly identifying info with advertisers without your request, your activity can still drive ad targeting and measurement.

Google provides account tools to review, export, delete specific items, delete product data, or delete the whole account. This gives users meaningful practical control compared with many services.

Users get dashboards like My Activity, Activity Controls, Ad Settings, browser controls, and device settings. These controls can limit saved activity, manage ad personalization, and review stored data.

Activity on other sites and apps that use Google services may be associated with your account, depending on settings. Practically, that can extend Google’s visibility beyond Gemini and Google-owned properties.

Google keeps some data until you delete your account, and other data may be retained longer for legal, security, fraud, or business reasons. Deletion may also be delayed while backups and active systems are cleared.

Google says it does not share personal information outside Google except for consent, admins, processors, legal reasons, or business transfers. That is more protective than policies that broadly allow sale or unrestricted third-party sharing.

Google promises it will not reduce rights under the Privacy Policy without explicit consent and will provide notice of significant changes. That is a user-friendly limitation on unilateral erosion of privacy protections.

If you use a school or work Google account, your administrator may access stored information, change settings, suspend access, and limit deletion or privacy controls. That reduces privacy and autonomy compared with a personal account.

Google expressly warns that Gemini may generate inaccurate or offensive content and should not be relied on for professional advice. Users bear the practical risk of verifying outputs before use or publication.

The terms prohibit using Gemini to develop machine learning models or related technology. This mainly affects developers and businesses hoping to repurpose outputs or service use for competing AI development.

The service is provided as-is, with broad warranty disclaimers and major limits on GitHub’s liability for losses, downtime, or data issues. If Copilot or GitHub causes harm, your remedies may be very limited.

Copilot inputs and outputs can be used to develop and improve GitHub and affiliate AI models unless you opt out. This matters if you do not want prompts, code context, or generated outputs used for model improvement.

Even though you keep ownership, GitHub gets broad rights to host, copy, analyze, display, and use your content to run and improve the service, including AI-related improvement. For public content, other users can also view and fork it under platform rules.

GitHub expressly says private repository contents are confidential and limits staff access to listed situations like security, support, service integrity, or legal compliance. This is a meaningful protection for non-public code.

GitHub says eligible users can access, correct, delete, restrict, object to processing, withdraw consent, and receive portable copies of their data. These are strong, user-helpful privacy rights.

GitHub warns Copilot output may be inaccurate, incomplete, vulnerable, or resemble third-party code, and puts review responsibility on you. Users cannot rely on output being safe or license-clean.

GitHub collects account data, content, device and usage data, cookies, support data, geolocation, and information from third parties. That gives the company a broad picture of your activity across the service.

Data may be shared with affiliates including Microsoft, service providers, partners, authorities, and in some cases advertising and analytics networks. The policy also says some personal information is "shared" for marketing and audience measurement under applicable law.

You can opt out of having Copilot inputs and outputs used for AI model development going forward. This is a practical privacy control, though it does not undo broader repository-content licenses elsewhere in the terms.

Account cancellation is described as a simple self-serve flow, and GitHub says it will generally delete your full profile and repository contents within 90 days, subject to backups and legal exceptions. You can also request a copy of account contents within 90 days.

GitHub offers multiple ways to reject non-essential cookies, including settings links, browser controls, Do Not Track, extensions, and Global Privacy Control. It also states it does not sell data and will not share data when GPC is detected.

GitHub promises advance notice for material changes to both the terms and privacy statement. That gives users some time to review updates before they take effect.
