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 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.

Reserving a Founders spot holds a place in line; no payment is taken and no payment details are collected. A reservation stores your email address (taken from your account when you are signed in, or typed by you when you are not), the time you reserved, the random browser identifier described above, and, only if you choose to write one, the first question you would ask your chart. For signed-in accounts Basis also records that the Founders offer was shown and how it was answered, so it is not shown again on another device.

We use the address to send you one email, when Founders opens. It is not added to a newsletter or a marketing sequence, and it is not shared beyond the providers that store it and deliver that email. Questions you write help decide what the question engine answers first; they are not published with your name or address.

Reservations are kept while the Founders programme is open. You can ask for yours to be removed at any time by writing to ops@basischarts.com.

Founders checkout requires a signed-in account. Card payment through Creem is the primary option; cryptocurrency through NOWPayments is optional. For crypto, starting checkout creates an order linked to your account that records the price, status, invoice and payment identifiers NOWPayments assigns, and the times it was created, updated and paid. Basis sends NOWPayments the order identifier, the price and a description of the product; it does not send your email address, name or other account details.

You choose the cryptocurrency and pay on the NOWPayments page, under NOWPayments’ own terms and privacy policy. Wallet addresses and transaction details are handled by NOWPayments and by the blockchain you pay on, which is public by nature; Basis does not store them and never asks for a wallet key or recovery phrase. A completed payment adds a Founders membership to your account, recorded with its member number, its start date and how it was granted. Payment records are kept for as long as accounting, tax and dispute-resolution obligations require, including after an account is closed.

Creem sells the membership to you as merchant of record and handles the card payment, sales tax, receipt and card refunds under its own terms and privacy policy. For a card payment Basis sends Creem the order identifier, the plan and the email address of your Basis account, so the receipt reaches you; your card details go to Creem only and Basis never sees them. The order records the price, its status, the checkout and order identifiers Creem assigns, and the times it was created, updated and paid, and is kept on the same terms as the crypto orders above. Payment support may require sharing order details with the relevant provider to investigate a refund or dispute.

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.

The Founders assistant is an AI that answers questions about the membership. If you ask it something, the messages of that conversation are sent to Groq, Inc., which runs the language model, to produce the answer, and Basis stores each question and its answer for 90 days with the time, the page and the random browser identifier described above (and your account, if you are signed in), so that a person can check what the assistant said and improve it. To stop one visitor from flooding it, the assistant counts questions per network address: the address is turned into a keyed hash for that count and is not itself written to our database, and a count is deleted once it is more than two days old, the next time the assistant is used. Do not type passwords, card details or other sensitive information into it. The conversation itself is kept in your browser only until you close the tab.

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, email, analytics, payment processing 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.

Telegram alerts, for Founders who turn them on: an alert set to Telegram is sent by the Basis bot to the chat you linked; the message carries the alert’s name, your note, what matched and a link to the chart. Basis stores that chat’s identifier and the Telegram name shown in it, and Telegram processes the message under its own terms. Disconnect in delivery settings or send /stop to the bot to unlink the chat. Alerts set on a drawing keep a copy of the drawing’s anchor points with the alert, so it can be checked with Basis closed.

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 by writing to ops@basischarts.com. 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, write to ops@basischarts.com 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, write to ops@basischarts.com and mark the subject as a privacy request.
