Your research is yours. Here is what Basis handles.

This policy explains how Basis handles information when you visit basischarts.com, use the terminal, create an account or contact the team. Basis is operated by an independent five-person team and is designed to collect only the information needed to run, secure and improve the service.

Basis does not sell personal information and does not use personal information for third-party behavioural advertising. Market research may be used without creating an account; an account is needed only for features that save or synchronize work.

The information Basis processes depends on the features you choose to use.

Basis uses browser storage so charts and research can work before an account is created. Local settings and unsynchronized work remain in that browser unless you clear them. When you sign in, supported collections can be synchronized to your account so they are available on another device.

Bring-your-own AI provider keys are stored on your device. By default a key is kept only for the browser session; remembering it across restarts is an explicit choice. The key is sent only to the AI provider you select, never to Basis servers, and is excluded from synchronized documents and assistant code.

Basis uses information only where it is reasonably necessary to provide the service, honour a request, protect the platform or understand whether the product works. Depending on local law, the basis may be performance of the service you requested, legitimate interests in security and improvement, consent, or compliance with a legal obligation.

Basis shares information only with providers needed to operate the service, such as hosting, database, authentication, analytics and web-push infrastructure. Those providers process information under their own terms and security controls. Basis may also disclose information when required by law, to protect users or the service, or as part of a future organizational transaction with appropriate safeguards.

Market venues, news sources and other public-data providers receive the network requests needed to load their data. If you choose an AI provider, your prompts, relevant chart context and provider key are sent to that provider so it can answer. Their privacy policy applies to that processing. Basis does not control third-party sites reached through external links.

Account records and synchronized research are retained while the account is active or as needed to provide the requested feature. Sessions expire and may be removed earlier when you sign out or for security reasons. Operational logs, analytics and backups may be retained for limited periods under the settings and lifecycle controls of the relevant service provider.

You can remove local browser data through the relevant Basis control or your browser settings. You may request access, correction or deletion of account information through the Support link in the terminal. Some information may be retained where required for security, legal compliance, dispute resolution or backup integrity, then removed according to the applicable retention cycle.

Depending on where you live, you may have rights to access, correct, delete, restrict or object to processing of personal information, receive a portable copy, or complain to a data-protection authority. Basis will verify requests before acting on them to protect the account. You can also use the terminal without an account, decline to remember an AI key, disable browser notifications and disconnect Google access through your Google account settings.

Basis uses measures including hashed passwords, hashed server-side session tokens, secure cookies in production, access controls and validation at application boundaries. No online service can guarantee absolute security. Infrastructure providers may process information in countries outside your own; where required, transfers are handled through the safeguards offered by those providers and applicable law.

Basis is intended for adults and is not directed to children under 18. We do not knowingly collect personal information from children. If you believe a child has provided account information, contact the team through Support so it can be reviewed and removed.

This policy may change as Basis adds features, providers or legal obligations. Material changes will be reflected on this page with a new review date and, where appropriate, an in-product notice. For privacy questions or requests, use the Support link inside the Basis terminal and clearly mark the message as a privacy request.
