Hosting

The NuxGrid service is hosted by 1&1 IONOS SARL, 7 place de la Gare, BP 70109, 57201 Sarreguemines Cedex, France. Telephone: +33 (0)805 54 21 80.

Purpose of the service

NuxGrid is Bitcoin grid trading software with a bot executed locally through the connector. The connector calculates GRID levels and executes orders on the user’s configured exchange, while NuxGrid.com provides the web console used to configure, control and monitor strategies. NuxGrid is neither an exchange, nor a financial institution, nor a funds custody service.

Intellectual property

The structure, software, graphic elements, texts and distinctive signs of NuxGrid are protected by applicable intellectual property rules. Any unauthorized reproduction or reuse is prohibited, except with prior agreement or where permitted by law.

Liability and contact

The publisher takes reasonable steps to maintain the service, but does not guarantee permanent availability or the absence of errors or interruptions.

For questions about the service or to report a security issue, use the Support feature available from your NuxGrid account. You can also write to contact@nuxgrid.com without signing in to your account.

Data controller

The data processing described here is carried out by the NuxGrid publisher to provide, secure and administer the service. For any request concerning your data, use the Support feature available from your NuxGrid account. You can also write to contact@nuxgrid.com without signing in to your account.

Data used

NuxGrid uses the login identifier, password hash, account role, account status, and creation and last-login dates.

To create a standard account, the form currently requests only a username and password. NuxGrid does not require an identity document, postal address, telephone number or email address.

For connector operation, the server retains the following metadata: the name chosen by the user, public key, status, version, synchronization activity and desired strategy configuration. The machine hostname is not used.

The desired configuration may describe the trading strategy (market, amount, spacing, profit target and associated options), but does not contain exchange secret keys, available capital or executed orders.

For login attempts recorded by the application, the IP address is replaced with a technical fingerprint to limit abuse. Security logs may be retained for as long as needed for their purpose.

Orders, capital and trading data

The connector’s local database is the source of truth for orders, executions, balances, available capital, metrics and trading events. This data is not stored permanently in NuxGrid server operational tables.

To display the dashboard, the server may relay a snapshot requested by the browser. This snapshot may contain the orders, metrics and capital needed for display, but the technical relay record is deleted after consumption and is not used as a server-side history.

The browser may locally retain the latest snapshot in IndexedDB to display the dashboard when the connector is temporarily unavailable. This storage remains under the user’s control and can be deleted through the browser’s site data.

Exchange security and secrets

Exchange keys are encrypted in the browser before transmission. The server never receives the values in plaintext; the encrypted envelope may be temporarily relayed to the connector and its contents are erased after validation or revocation.

After validation, usable keys are installed locally on the connector. They are not included in metric or order synchronizations.

Account passwords are stored as hashes and are not kept in plaintext.

Purposes and legal bases

Account management, authentication, connector synchronization, console display, purchase processing, support and requested notifications are based on performing the requested service.

Service security and abuse prevention are based on the legitimate interest in protecting NuxGrid and its users. Retention of records required by regulations is based on applicable legal obligations.

Recipients and third-party services

Data is accessible only to people authorized to administer NuxGrid and providers needed for its operation, notably the IONOS host.

When the user configures a connector or an exchange, strictly necessary data may be transmitted to the explicitly configured device and, for real orders, to the exchange selected by the user. No public or advertising-related sharing is planned.

Sharing between accounts is optional and limited to the active positions needed for the shared view. It does not turn the server into an archive of orders or balances.

Cookies and trackers

The application uses a session cookie strictly necessary for authentication and session maintenance. It is deleted when the session closes or expires.

NuxGrid currently uses no advertising cookie, profiling tool or audience measurement tool requiring consent.

A language preference cookie remembers your selected language for one year.

The browser may also remember display preferences and a copy of the latest dashboard state. You can delete this information in your browser settings; some preferences and display data will then be lost.

Retention and requests

Accounts, connector metadata, configurations and associated data are retained for as long as necessary to operate the service, ensure security and comply with applicable obligations. Trading orders, balances and metrics remain in the connector’s local storage and, where applicable, the browser’s local storage.

Dashboard snapshots relayed by the server are temporary transport data. They are deleted after reading; expired requests and old results are cleaned up when new requests are made. They do not constitute a durable server-side history.

Login attempts older than two days are purged when a new attempt is recorded. Security logs, support tickets and payment references currently have no automatic purge; retention serves follow-up, security and applicable legal obligations.

Completed or failed private backtests become eligible for deletion after the configured period, 48 hours by default, measured from completion or creation when no completion date is available. Cleanup occurs when the backtest area is accessed. Published backtests are exempt from this purge.

Connector backup exports pass through a temporary server file, deleted when request processing finishes. The downloaded copy remains on your device, where you control its retention. Telegram association codes are valid for 15 minutes. Expired or used codes are cleaned up when a new code is created. Data retained by Stripe, Telegram, your exchange and your own connector is also subject to their rules and your settings.

The retention periods selected for general contact enquiries unrelated to a purchase or dispute are one year after the enquiry is closed, and 90 days from creation for operational backups of the NuxGrid server. This backup period does not apply to copies kept on your device or to your own connector.

Commercial correspondence has a selected retention period of five years from the last exchange; invoices and accounting evidence have a period of ten years from the end of the relevant financial year. Documents needed for a dispute may be retained for the time required to handle it and meet applicable obligations.

For a request for access, rectification, erasure, restriction or objection, use the Support feature from your NuxGrid account. You can also write to contact@nuxgrid.com without signing in to your account.

Your rights

Under the conditions provided by applicable regulations, you may request access, rectification, erasure or restriction of processing, object to certain processing and recover your data where the right to portability applies.

To exercise your rights, use the Support feature in your NuxGrid account. You may also lodge a complaint with the Commission nationale de l’informatique et des libertés (CNIL). You can also write to contact@nuxgrid.com without signing in to your account.

Stripe payments

Extension purchases are processed by Stripe on its payment page. Stripe collects the information needed for payment, which may include your email address and billing information.

NuxGrid sends Stripe a reference linked to your account and selected extension. NuxGrid retains the references needed to confirm payment and activate the extension. Your full payment card details are not stored in the NuxGrid database.

Stripe may process data outside the European Union, including in the United States. Its privacy policy describes international transfers and the protection mechanisms it applies.

Telegram notifications

If you link Telegram to your account, NuxGrid retains the conversation identifier, your Telegram username when available, the linking date and your notification preferences.

Enabled notifications may send Telegram information about your purchases, sales, conversions and connector incidents. They may include trading amounts, prices and results. You can disable delivery in your preferences.

Telegram is a third-party service established outside the European Economic Area. Sent messages are also subject to its privacy policy and its processing and retention terms.

Support and correspondence

When you contact the built-in support or contact@nuxgrid.com, your messages, any contact details you provide and the technical diagnostics collected for your request are used to handle it.

Do not include passwords, exchange secret keys or recovery phrases in these messages.

Purpose of the service

NuxGrid provides a web console for configuring, controlling and monitoring Bitcoin grid trading strategies executed locally by the connectors. Orders, histories and balances are produced and stored locally by the connector; the server relays them to the dashboard occasionally when necessary.

Account and access

Each user is responsible for keeping their username and password confidential. Administrator accounts may manage access in accordance with the features available in the console.

Any unauthorized use or security anomaly must be reported as soon as possible through the Support feature in the NuxGrid account. You can also write to contact@nuxgrid.com without signing in to your account.

Trading and configurations

NuxGrid is a technical tool for configuring, controlling and monitoring Bitcoin grid trading executed by a bot running locally through the connector, according to the parameters configured by the user. Keys, orders and balances remain under the control of the connector installation and the selected exchange. NuxGrid is not financial advice and does not guarantee any trading result.

The user remains responsible for their choices, parameters, exchange keys, activation of real mode and orders sent through their connectors.

Crypto-asset trading carries a risk of losing part or all of the invested capital. Simulations and backtests do not guarantee future results. Execution depends on the connector, network connection, exchange and API permissions, among other factors.

Authorized use

The user agrees to use NuxGrid in accordance with applicable laws, not to attempt to bypass security measures and not to disrupt the operation of the service or connectors.

Availability and changes

Features may evolve, be corrected or be temporarily unavailable for maintenance, security or third-party service dependency reasons.

The publisher may suspend an account in case of abusive use, security risk or breach of these terms, subject to applicable rights.

Intellectual property

NuxGrid, its code, interface, content and graphic elements remain protected by applicable intellectual property rules. No right to reproduce or redistribute is granted outside normal use of the service.

Applicable law and contact

These terms apply subject to mandatory rules protecting the user. In case of difficulty, first seek an amicable solution through the Support feature in the NuxGrid account. You can also write to contact@nuxgrid.com without signing in to your account.

For any question about these terms, use the Support feature available from your NuxGrid account. You can also write to contact@nuxgrid.com without signing in to your account.

Scope and contact

These terms apply to paid NuxGrid extensions purchased from the catalogue. Version: 3 October 2026, revision 2. You can save or print this page before purchasing.

For a purchase enquiry or complaint, use the Support feature in your account or write to contact@nuxgrid.com, including your username and payment reference. Never send your full card number or secret keys.

Features and requirements

The extension page describes the included features and price before payment: Backtest Pro provides historical simulations, Reports & Exports provides reports and exports, and Notifications Pro provides Telegram notifications. The purchased extension is identified again on the Stripe payment page.

A NuxGrid account, a modern browser and an Internet connection are required. Features that use live connector data require an associated, available connector; Telegram notifications also require a Telegram account and its association with NuxGrid. Backtests and trading tools provide no guarantee of profit.

Price, payment and activation

Each extension is a single purchase with no subscription or automatic renewal. The catalogue displays the price payable and currency; Stripe shows the final amount and any currency conversion before you confirm payment. Sales covered by the French VAT exemption scheme are made without French VAT (Article L.223-3 of the French Code of Taxes on Goods and Services). Do not confirm if this amount does not match your intended purchase.

Payment is processed by Stripe. The extension is activated on the purchasing account after confirmation of successful payment. If activation fails or is delayed, contact Support with your payment reference; you do not need to purchase the same extension again.

Lifetime access and account recovery

“Lifetime” means that the purchased extension has no scheduled expiry and is linked to the account that purchased it. No recurring payment is required to keep this access. It is not automatically assigned to a newly created account.

If you lose access to your account, contact contact@nuxgrid.com before purchasing again. Recovery is examined using available proof of ownership, including the payment reference, without guaranteeing recovery when ownership cannot be verified. These terms do not limit mandatory consumer rights.

Withdrawal

Consumers have 14 days from conclusion of the purchase contract to withdraw without giving a reason. Immediate activation of the extension does not waive this right. To withdraw, send an unambiguous statement through Support or to contact@nuxgrid.com identifying the purchase concerned.

Following withdrawal, the amount paid is refunded within 14 days of receipt of the request, using the original payment method unless you expressly agree otherwise, without refund fees. Access to the refunded extension is then withdrawn; your other purchases remain unaffected.

Withdrawal form

Send to contact@nuxgrid.com: “I hereby notify you of my withdrawal from the contract for the following NuxGrid extension: [extension]. Purchased on: [date]. Payment reference: [reference]. Username: [username]. Consumer name and address: [name and address]. Date: [date].” A signature is required only for a paper submission. Use this form only if you wish to withdraw.

Legal guarantees

Backtest Pro, Reports & Exports and Notifications Pro are digital services supplied continuously from activation, with no scheduled expiry, under the account-linked access conditions described above. The legal guarantee of conformity covers this entire contractual supply period; it is not limited to two years.

To invoke the legal guarantees, contact Support in your account or contact@nuxgrid.com, identifying the extension and the defect encountered. These rights are distinct from discretionary refunds and are not excluded by trading risk notices.

Complaints and disputes

For a problem with an extension, first send a written complaint through Support or to contact@nuxgrid.com. The request is examined and, where warranted or legally required, a refund is made through Stripe.

Consumers have the right to seek free consumer mediation after an unsuccessful prior written complaint. No consumer mediator is currently designated for NuxGrid. Support and direct refunds do not replace this mechanism. You retain the right to bring proceedings before the competent court; no clause requires you to mediate first.
