Terms of Use and Hosted Nightscout subscriptions

1. Seller and Hosted Nightscout service provider

The seller of paid AI-balance top-ups and new paid Hosted Nightscout subscriptions under these terms is Individual Entrepreneur Dmitrii Vladimirovich Polianinov (ИП Полянинов Дмитрий Владимирович), registered in the Russian Federation. Taxpayer Identification Number (INN): 501208561949. State Registration Number of the Individual Entrepreneur (OGRNIP): 307501231000027. Support, subscription cancellation and refund requests: support@dia.best. Further contact information is on the Contacts page.

Edsofa is the payment-service channel for these subscriptions. The seller is the Russian individual entrepreneur identified above, not the separately registered Georgian individual entrepreneur. Publishing these details does not change the provider or terms of an existing contract retrospectively, activate Hosted Nightscout checkout or authorize a charge.

2. What you purchase

Hosted Nightscout is a digital hosting service: a separately hosted Nightscout instance and the technical infrastructure used to operate it. Payment is for hosting and support of that instance, not ownership of the Nightscout software, medicine or medical treatment. You connect a compatible data source; hosting alone does not establish the connection to a sensor.

Core Dia.best functionality and connecting your own externally hosted Nightscout remain free. Optional paid AI actions are separate from the hosting subscription.

3. Prices and billing periods

Annual: US$19 for one year, paid once. There is no automatic annual charge. Renewing requires a new confirmed annual payment.

Monthly: planned US$3 per month. Monthly automatic renewal is not available yet.

Prices are displayed as US dollar (USD) reference amounts. Edsofa shows the final payment amount and currency before you pay. The amount charged in your card currency may differ from the displayed USD reference amount.

4. First payment and service period

Paid hosting becomes available only after the relevant checkout is activated. The paid period and its end date are confirmed in your account or order confirmation. No hosting time should be lost solely because of a technical activation delay attributable to Dia.best; contact support to correct the period or request a refund. Renewing an active subscription extends the existing paid period.

5. Automatic renewal and your consent

A new monthly or annual subscription requires your explicit agreement to the displayed fixed RUB charge and automatic renewal every 30 or 365 days until cancelled. Your payment method is stored by the payment provider. Reading this page, signing in or using a free account does not authorize a charge. Changing a price or currency requires fresh consent and must not silently change an existing mandate.

Existing one-time annual purchases have no automatic renewal. Their saved payment and service terms remain unchanged.

6. Cancellation and payment methods

You may request cancellation of future renewal using the subscription controls in your account, or by contacting support@dia.best from your account email. You may also request removal of the saved payment method. Cancellation does not by itself request an immediate refund or end access for the period already paid for.

After cancellation, Dia.best must not initiate a new automatic renewal. A payment already submitted to a bank may be in progress; support will review any such charge. Refund and statutory withdrawal rights are separate and are explained in the Refund Policy.

7. Free accounts and existing Nightscout connections

This publication does not convert an existing free account into a paid subscription and does not authorize payment for past free use. Current free connections remain subject to their existing conditions. Connecting your own Nightscout is not a purchase of managed hosting.

8. Account credit and AI features

Each verified annual hosting payment includes a matching promotional account credit based on the verified payment value, for use with paid AI features. It is separate from the paid hosting period: spending the credit does not shorten that period. It is not a bank deposit or a separately purchased financial product.

One-time AI-balance top-ups, when available in your account, use Edsofa. Enter a US dollar (USD) reference amount. Edsofa shows the final payment amount and currency before you pay. Your AI balance receives the matching verified payment value. A saved checkout keeps its confirmed amount; a new checkout after a reference-price change requires new consent. The amount charged in your card currency may differ from the displayed USD reference amount. A balance top-up does not purchase Nightscout hosting and does not authorize automatic renewal or another card charge.

Changing the display language does not change your existing balance or paid hosting period. Current paid AI prices and introductory free uses are shown in your account. Dollar displays are reference values. For unused balances and refunds, see the Refund Policy.

9. Health-related data and limitations

Nightscout and Dia.best may process glucose and other health-related information according to the Privacy Policy. Keep account and connection credentials private. Dia.best is not a substitute for medical care, diagnosis or treatment. Do not rely on a remote server or a forecast as your only source for urgent diabetes decisions.

10. Refunds, changes and acceptance

See the Refund Policy. These terms do not exclude mandatory consumer rights. The terms shown at purchase apply to that order; new published terms do not create a retrospective charge or remove an already paid period. Confirming an order after being shown these terms constitutes acceptance. Support: support@dia.best.
