11.2. The Operator does not guarantee delivery of notifications within any specific time. Notifications are informational only.

11.3. Users may disable notifications at any time in the app settings or profile.

11.4. The Operator distinguishes three types of push notifications sent to the User:

(a) System notifications — operational messages relating to the Platform itself, in particular: information about new app versions, planned maintenance, changes to the Terms or Privacy Policy, critical security warnings, and price alerts configured individually by the User. These notifications are necessary for the proper use of the Platform and do not require separate marketing consent. They are sent under Art. 6(1)(b) GDPR (performance of the service contract). The User can disable them in the device's system settings or by deleting the account.
(b) Individual notifications — messages addressed directly to a specific User by the Operator in response to a report, support request, contact form question, or to provide account-related information. They are sent under the legitimate interest of the Operator and the User (Art. 6(1)(f) GDPR) and do not require separate marketing consent.
(c) Bulk notifications (marketing) — commercial, informational-promotional messages, Advertiser offers, sales-oriented feature announcements, quarterly reports, etc., addressed to a larger group of Users at once. They are sent only to Users who have given separate, voluntary and explicit consent in the app (Profile → Marketing notifications). Consent can be withdrawn at any time in the same place, without affecting the lawfulness of processing prior to withdrawal. The legal basis is Art. 6(1)(a) GDPR and Art. 10 of the Polish Act of 18 July 2002 on the provision of services by electronic means.

11.5. The Operator does not use the push token for any purpose other than sending the notifications described above. The token is not shared with third parties except the push delivery operator (Expo Push Service / Google FCM / Apple APNs) strictly to the extent technically required to deliver the notification.

11.6. The frequency of bulk (marketing) notifications is limited. The Operator commits not to send more than one bulk notification per day to the same User and not to send such notifications between 22:00 – 07:00 of the User's local time.

11.7. Every marketing notification contains, in its body or on the accompanying screen, the identity of the sender ("VoltAlert / Samael Sp. z o.o.") and a link allowing the User to quickly turn off this type of notification.

§12. Fees

12.1. Use of the Platform by individual Users is free of charge.

Using the Platform in accordance with applicable law and these Terms;
Not undertaking actions that disrupt the Platform's operation;
Not automating requests to the Platform (scraping, bots) without the Operator's consent;

15.3. Any public distribution, retransmission, publication, scraping or commercial use of Platform data is strictly prohibited without prior written consent from the Operator.

15.4. For non-commercial, educational or informational citation of Platform data, the following is required: (a) clear attribution to "VoltAlert (voltalert.pl) / ENTSO-E"; (b) a link to voltalert.pl; (c) prior notification to the Operator at biuro@samael.pl.

15.5. Violation of the above entitles the Operator to claims under Polish copyright law, unfair competition law, GDPR and other applicable legislation.

15.6. Price data originates from ENTSO-E, which also has its own rights and restrictions on further use of data.

Users may delete their account at any time in the app or at voltalert.pl/delete-account.html. The operation is irreversible. Data is permanently deleted in accordance with the Privacy Policy.

§17. Service availability

The Operator strives to ensure continuous Platform availability but does not guarantee the absence of technical interruptions. Planned maintenance will be communicated in advance.

§18. Amendments

The Operator may amend these Terms with 14 days' prior notice. Registered Users will be notified by email. Continued use of the Platform after the effective date of changes constitutes acceptance.

§19. Complaints

Complaints should be submitted to biuro@samael.pl with a description of the issue. The Operator handles complaints within 14 business days.

§20. Governing law and dispute resolution

These Terms are governed by Polish law. The competent court is the court of general jurisdiction for the Operator's registered seat. Consumer Users may use the EU ODR platform: ec.europa.eu/consumers/odr.

§21. App stores (Google Play and App Store)

21.1. By downloading the App from an app store (Google Play or the App Store), the User is additionally subject to that store's terms. In the event of a conflict regarding use of the App, the mandatory requirements of the relevant store prevail.

21.2. Applies to the iOS version. The User and the Operator acknowledge that these Terms are concluded between the User and Samael Sp. z o.o., and not with Apple Inc. ("Apple"). Samael Sp. z o.o. is solely responsible for the App and its content. Apple has no obligation to provide any maintenance or support services for the App.

21.3. If the App fails to conform to any applicable warranty, the User may notify Apple, and Apple may refund the purchase price of the App (the App is free of charge). To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. This does not affect consumer rights under mandatory law.

21.4. Apple is not responsible for addressing any claims of the User or any third party relating to the App or its possession and use, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, consumer protection claims, and intellectual property infringement claims. Samael Sp. z o.o. is solely responsible for such claims.

21.5. The User represents and warrants that they are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that they are not listed on any U.S. Government list of prohibited or restricted parties.

21.6. Apple and its subsidiaries are third-party beneficiaries of these Terms with respect to the iOS version and, upon the User's acceptance of these Terms, have the right (and will be deemed to have accepted the right) to enforce these Terms against the User as a third-party beneficiary.
