FAIR USE POLICY

Last modified: 09/08/2026

I. OPERATING REGULATIONS

These Operating Regulations (hereinafter "Regulations") define the terms and procedures for the use of the SyncSignal application. The aim of the Regulations is to clearly describe the way in which the application's services operate, the requirements for account creation and management, the settings associated with the Signal function, as well as the obligations of users. These Regulations constitute a supplement to the Terms of Use and the Safe Use Policy and apply to all users of the application. Understanding and complying with these Regulations is necessary for the smooth and safe operation of the SyncSignal application, as well as for the protection of users and their personal data.

A. User Account

1. To use the SyncSignal application, the creation of a user account is required. Upon registration, the user provides:

  • full name,
  • mobile phone number,
  • email,
  • age,
  • gender (male/female/non-binary/other/prefer not to answer),
  • password.

2. Upon registration, the user:

  • provides true, complete, and accurate information,
  • declares that they are over 15 years of age,
  • accepts the Terms of Use, the Fair Use Policy, and the Privacy Policy.

3. SyncSignal may ask the user to verify their email and/or phone number. Access to certain functions (such as the Signal button or Signal notifications) may require identity confirmation via SMS or email.

4. The user is obliged to keep their account details fully updated, especially their email and mobile phone number. SyncSignal bears no liability for failure of notifications or functions when due to incorrect or outdated information.

B. Account Deletion

1. The user may discontinue using the application and delete their account at any time through the SyncSignal settings. Upon deletion, all account data is terminated and managed in accordance with SyncSignal's Data Retention and Destruction Policy.

2. SyncSignal may suspend or terminate the user's access to the application if:

  • there is a violation of the Terms of Use or the Fair Use Policy,
  • false or misleading provision of information upon registration is found,
  • abuse of the Signal function or other harmful use is detected,
  • required by law, a judicial or administrative authority,
  • there is a reason of system or user security.

Where feasible, the user is informed before or immediately after the implementation of the termination.

3. Upon deletion:

  • The user loses access to the application's functions.
  • Data is deleted or anonymized in accordance with the Privacy Policy and the Data Retention and Destruction Policy.

4. Terms that by their nature remain in force continue to apply even after termination.

C. Close Friends

1. "Close friends" are the persons the user designates within the application to receive their Signal notifications. Close friends must have an account on the application. The user can define up to two (2) close friends on the free plan and up to five (5) with the SyncSignal Pro subscription (in total, together with their other friends, up to 30 friends are supported). Close friends must explicitly accept the invitation through the application in order to receive Signal notifications.

2. In case of a Signal activation, close friends receive the user's location and audio in real-time; if the user holds a Pro subscription, they also receive video. This sharing takes place exclusively for purposes of protecting life and physical integrity.

3. Close friends must use the data they receive only for the provision of assistance and never for purposes of surveillance, intimidation, or any other impermissible behavior. SyncSignal bears no liability for misuse of data by close friends.

4. The user can add, remove, or replace their close friends at any time through the application settings. Those removed cease to receive Signal notifications.

5. Any close friend may withdraw their acceptance at any time through the application or via a relevant link provided in the invitation. Upon withdrawal, they are deleted from the user's close friends list.

6. SyncSignal does not guarantee that close friends will always be available, that they will respond, or that mobile/data networks will operate uninterruptedly.

7. The service is provided as a supportive safety mechanism and does not substitute official emergency services (e.g., 112, 911).

D. Notification of Users Nearby

0. The nearby-users notification feature is not currently available. The following will apply if and when the feature is activated:

1. SyncSignal informs, in case of a Signal activation, users located within a radius of up to 1 kilometer that there is a danger incident in the area. This function is activated exclusively for information and prevention purposes, without any obligation of reaction by these users.

2. Users nearby receive only basic information:

  • the exact location of the incident, and
  • the declared gender of the user (if selected) who activated the Signal.

Images, audio, name, account details, or any other personal data are not shared.

3. Users receiving a notification must:

  • not use it for aggressive, intrusive, or harmful behavior,
  • not approach dangerous areas without reason,
  • not use the information for identification or tracking of another user.

The application neither urges nor requires any action from the notified user.

4. SyncSignal does not guarantee that all notifications will be delivered, as there may be delays or failures due to technical network limitations, GPS, or push notification providers. The function does not substitute calling 112 or other official emergency services.

5. SyncSignal is solely a communication tool and under no circumstances constitutes a police service, immediate rescue or medical intervention service, or any governmental emergency service, nor does it cooperate with or have any affiliation with such services. When a user activates a Signal, no competent Authority, service, or body with an obligation to provide assistance is automatically notified — only the close friends the user has approved are notified (and, where the relevant feature is offered, other SyncSignal users nearby). SyncSignal does not guarantee that close friends and/or other users will respond to any Signal sent by the user.

The use of SyncSignal's services does not replace calling official emergency numbers (e.g. 112, 911, or local equivalents), and users are encouraged in every emergency or danger situation to immediately notify the relevant competent authorities.

E. Location Sharing — Quick Sync, Live Sync

1. The application provides functions for the voluntary sharing of location outside emergencies:

  • Quick Sync: a one-off share of the current position with a friend of the user's choice, with an optional mood symbol and the ability for the friend to reply with their own position. A short time limit applies between consecutive Quick Syncs to the same friend.
  • Live Sync: continuous sharing of position with friends the user selects, for a duration they set (1 hour, until the end of the day, or until revoked), with the battery level shared as well. Freely revocable, per friend or entirely, at any time.

2. Every share is activated exclusively by the user's own action, for themselves. Recipients must use the information exclusively within their relationship of trust and never for purposes of surveillance, control, or intimidation (see Part II).

II. SAFE USE POLICY

This Safe Use Policy defines the set of rules and restrictions governing the use of the SyncSignal application, with the aim of preventing abusive behaviors and protecting the personal safety of users. This policy specifies the obligations of users when using the Signal function, the location-sharing functions, and other tools of the application, ensuring that these functions are used responsibly, legally, and with respect towards third parties. The Safe Use Policy operates supplementarily to the Terms of Use and the Operating Regulations of the application and aims at creating a safe and reliable environment for all SyncSignal users.

A. Proper use of the Signal function

1. The user is obliged to activate the Signal button only in real or reasonable situations of danger. The intentional sending of false or misleading Signals, as well as the abuse of the function, are prohibited and may lead to suspension or deletion of the account.

2. Notifications to users nearby (where the relevant feature is offered) are intended exclusively for informing individuals in case of potential danger. The user is not allowed to use them in a way that may create confusion, harassment, or cause distress without real cause.

3. During a Signal activation, audio and video from the user's surroundings may be recorded. The user remains responsible for complying with applicable law where the recording involves third parties.

B. Prohibited behaviors

1. The application is not allowed to be used for harassment, stalking, surveillance of third parties, or any form of aggressive, abusive, or illegal behavior.

2. Any use of the application is prohibited which:

  • violates legislation, moral ethics, or the rights of third parties,
  • aims at harassment, intimidation, surveillance, or circumvention of another person's privacy,
  • is used as a tool for monitoring, controlling, or coercing other persons, including family members, partners, or acquaintances,
  • uses the application with the intent of causing panic, confusion, or a false impression of danger,
  • abuses the Signal function or notifications to other users,
  • abuses the location-sharing functions (Quick Sync, Live Sync) for the surveillance, control, or coercion of third parties,
  • aims at unauthorized access to third-party data.

Any such behavior constitutes a serious violation of the Terms and may lead, at SyncSignal's absolute discretion, to suspension or deletion of the user's account.

3. The user is not allowed, in any way, to use the application for monitoring, recording, or collecting third-party data without their consent, as provided by personal data protection legislation.

4. The application is not allowed to be used as a tool for monitoring, controlling, or coercing other persons, including family members, partners, or acquaintances.

C. Company actions in case of violation: In case of violation of the obligations defined in this policy, the company may proceed to:

  • warning the user,
  • restriction of functions,
  • temporary suspension or permanent deletion of an account.

In serious cases, the competent authorities may be informed.

D. Obligation to report abuse: Users are encouraged to immediately report to the company any incident they consider constitutes misuse of the application or violation of the terms. Reports can be made via support email or through the relevant function in the application.
