Mistral AI vs ChatGPT

Mistral may use your prompts and outputs to train models on free subscriptions and some Le Chat paid plans unless you opt out. That means your AI interactions may help improve the model by default in those cases.

EEA consumers can bring claims in their home-country courts or in Paris, and mediation is voluntary rather than forced. This preserves the practical right to sue in court.

You can object to use of your input/output for model training directly in account settings. This gives users a meaningful privacy control without needing to contact support first.

Mistral provides self-serve controls to export data and delete your account, plus a switching process to move to another provider. This improves portability and makes exit less burdensome.

Le Chat inputs and outputs may remain stored until you delete the conversation or your account. If you do not actively clean up chats, they can persist indefinitely.

Some account-related records are retained for years, including invoices for 10 years and certain identity/support records for 5 years. Even after account deletion, not all data disappears immediately.

Mistral may automatically monitor use, review content, and remove or restrict data or suspend accounts for breaches, legal compliance, or risk. This can be important if you rely heavily on the service.

For covered U.S. users, Mistral says it did not sell, share, or use personal data for targeted advertising in the past 12 months. This is a favorable signal against ad-tech style exploitation.

Paid plans renew automatically until canceled, and cancellation only stops the next renewal rather than producing a prorated refund. Users need to cancel in advance to avoid another charge.

Payments are generally non-refundable, although EEA consumers do get a 14-day withdrawal right. After that window, canceling usually just preserves access through the current term.

The company excludes liability for unforeseeable losses, losses not caused by its breach, and events beyond its control, while preserving non-excludable consumer rights. That may narrow recovery for some service problems.

Mistral may update the terms and privacy policy over time. The terms promise 30 days' notice for material changes, which is better than silent updates but still allows unilateral changes.

Users can delete chats, delete accounts, export data, use temporary chats, and manage memory settings. Deleted personal data is generally removed within 30 days unless an exception applies.

OpenAI can use your prompts, uploads, and outputs to develop and improve services, including model training, unless you opt out. This creates a meaningful privacy tradeoff for sensitive chats.

Disputes can go to your local courts, which is more user-friendly than mandatory arbitration or class-action waivers. EEA users also get access to an EU dispute resolution platform.

The terms explicitly say consumer rights under applicable law are not waived. This helps protect users against overbroad contract terms.

Users retain ownership of their input and, where legally permitted, own the output assigned by OpenAI. That is stronger than services that claim broad ownership over user-generated results.

You can turn off use of your content for model training in account settings. This is a significant privacy control, even though it is not the default.

The privacy policy allows collection of account data, payment data, prompts, files, contacts, device, usage, cookies, location, and some outside-source data. Users should assume extensive telemetry and content processing.

Although deletion tools exist, OpenAI may keep data longer for legal, security, fraud, abuse, and accounting reasons, and de-identified training data may remain disassociated from your account. So deletion is not always immediate or absolute.

If you use an employer or business-linked account, administrators may control the account and access your content, and your organization may learn you have the account. That reduces privacy in workplace contexts.

Material adverse changes to the terms require at least 30 days' advance notice. This is better than immediate unilateral changes without warning.

Paid plans renew automatically until canceled. After the 14-day cooling-off period, cancellation usually stops future charges but does not refund the remaining billing period.

Personal data may be processed outside Europe, including in the United States, using adequacy decisions or standard contractual clauses. This is common, but some users may prefer local-only processing.
