What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Protect your personal data by sharing the minimum information an AI tool needs, removing identifiers that are not essential, and keeping passwords, authentication codes, and unapproved confidential material out of prompts. Before using a tool, check the privacy controls and terms for the exact service and account you’re signed into; training, storage, human review, and deletion are separate issues.
What should you keep out of AI prompts?
Treat every prompt as a disclosure to the service. The same applies when you upload a file, share a screenshot, use voice or video, share your screen, provide browser context, or connect another app. Before sending anything, ask whether the tool needs that detail to answer.
- Never enter credentials: passwords, one-time passcodes, API keys, recovery codes, and payment credentials.
- Remove unnecessary identifiers: replace names with roles or placeholders, and generalize dates, locations, employers, and case details when those specifics are not needed.
- Be especially cautious with sensitive information: health, financial, legal, employment, and children’s information should go only through a service and workflow approved for that information.
- Do not paste other people’s sensitive details unless you have a legitimate reason and the tool and workflow are authorized to handle them.
For example, instead of pasting a named employee’s full performance record, you might describe an anonymized scenario and ask for general feedback language. Redaction lowers exposure; it does not change the service’s data practices.
Which privacy settings and terms should you check?
First identify the exact product and account: a provider’s personal assistant may have different terms from its work, school, or business offering. Then look for controls and documentation covering each of these questions:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Model improvement or training: Can your conversations or submitted content be used to improve models, and is there a setting to control that?
- Chat history and activity: What is saved to your account, and can you use a temporary or history-off mode?
- Memory and personalization: Does the service retain details to personalize later responses, and can you review or delete them?
- Retention and deletion: How long can data remain, and are there exceptions for security, legal requirements, or human review?
- Uploads and integrations: What can files, connected apps, browser context, voice, or screen features expose?
These are distinct controls. Turning off model training does not necessarily stop a service from processing a prompt to produce an answer, logging it, retaining it for security, or allowing a limited review under its terms. Deleting activity may also differ from erasing every copy held for a documented purpose.
How do privacy practices differ across common AI services?
These examples come from the providers’ own documentation and are not a ranking. Features, eligibility, defaults, and terms can change; check the current page for the account and region you use.

ChatGPT and OpenAI services
OpenAI describes controls for whether ChatGPT conversations help improve its models, as well as options to delete memories, conversations, and account data. It also describes encryption at rest and in transit and advanced account security. These are OpenAI’s statements about its service, not independent test findings. See OpenAI’s security and privacy information.
Do not apply API terms to consumer ChatGPT. OpenAI says API data is not used to train or improve models by default, but its documentation says API abuse-monitoring logs may contain prompts, responses, and derived metadata and are retained for up to 30 days by default, subject to exceptions for legal requirements or service protection. Eligible organizations can seek Zero Data Retention or Modified Abuse Monitoring controls. See OpenAI API data controls. OpenAI also says business, education, and API data is not used for training by default; applicable terms and controls depend on product and eligibility. See OpenAI business data information.

Microsoft Copilot
Microsoft distinguishes consumer Copilot from Copilot Chat used while signed in with a work or school account. For work or school Copilot Chat, Microsoft says prompts and responses are not used to train foundation models, while prompts, triggered Bing searches, and responses are logged. Enterprise data protection does not mean there is no logging or administrator governance. For consumer Copilot, Microsoft describes a conversation-activity control for signed-in users; its FAQ says future conversations are excluded from model training after opting out and distinguishes use while not signed in. Consult Microsoft’s Copilot privacy FAQ for current details.
Google Gemini Apps
Google’s Gemini Apps Privacy Hub describes prompts and shared content such as files, videos, screens, photos, imported chats, and browser page content; connected apps and other Google-service information may also be involved. Google says Gemini Apps Activity auto-delete defaults to 18 months and can be changed to 3 months, 36 months, or indefinite, or activity can be deleted manually. Google further says chats reviewed by human reviewers and associated information are not deleted when activity is deleted and may be retained for up to three years. These are Google’s product-specific terms, not a rule for other assistants. See Google’s Gemini Apps Privacy Hub.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
Connected apps deserve particular care: Google says Gemini activity that includes connected-app information may be used to improve Google services, including training generative AI models, when Keep Activity is on. The company says summaries, excerpts, and inferences from relevant connected data may be used, and advises against connecting apps with confidential information you would not want used for training or seen by a reviewer. See Google’s information about connected apps and Gemini Apps Activity.

Use only an organization-approved account and workflow for work, customer, or client information. A work or school account may offer different protections from a personal account, but organizational controls can coexist with logging, administrator access, and retention policies. Follow your employer’s data-classification rules and ask its administrator or privacy/security contact which tools and data types are approved. OpenAI says business, education, and API data is not used for training by default, while Microsoft describes enterprise data protection for eligible work or school Copilot Chat use; neither statement replaces your organization’s policy.

How can you reduce exposure beyond the prompt?
- Review files and screenshots for names, account numbers, email addresses, metadata, or unrelated material before uploading.
- Disable connected apps and integrations you do not need. Do not connect a source containing confidential material unless your policy allows it.
- Use a unique password, enable multifactor authentication when available, and protect the recovery email on the AI account.
- Delete chats or activity when appropriate, but do not assume deletion instantly removes data retained for review, security, legal, or other documented purposes.
- Revisit privacy settings and notices periodically because product features and defaults change.
What does U.S. consumer-protection guidance say?
In January 2024, the U.S. Federal Trade Commission warned companies about retaining or using consumer data for other purposes without clear, conspicuous notice and affirmative express consent. The FTC said that burying disclosures in hyperlinks, legalese, or fine print—or changing terms surreptitiously—may risk violating the law. This is U.S. agency guidance about company practices, not a substitute for advice about a particular service or jurisdiction. Read the FTC statement.
