3.2 User Behavior Analysis
We analyze your in-app behavior, such as how often you use the app, which features you interact with, and your completion of fitness goals. This data is used to refine app design, improve workout tracking features, and adjust content for greater user engagement and motivation.

3.6 Data Analytics and Statistics
We use aggregated, anonymized data to generate statistical insights, identify trends, measure performance of different fitness plans, and improve recommendation algorithms. These analyses do not personally identify you and are used for internal product optimization purposes.
At Siso, we are committed to providing a safe and secure experience for all users. In line with this commitment, we have implemented strict age-related policies to protect minors. Siso is intended exclusively for individuals who are 18 years of age or older. By using the app, you affirm that you are 18 or older. If you are under the age of 18, you are prohibited from using Siso, and we request that you do not attempt to register or provide any personal information.
We do not knowingly collect or solicit any personal data from individuals under the age of 18. We do not offer services or content specifically intended for minors. If we discover that we have unintentionally collected personal data from a minor, we will take immediate steps to remove such data from our records and terminate any associated accounts.
During the registration process, users are required to confirm that they are 18 years of age or older. This is a necessary step to ensure compliance with our age restriction policy. If we find that a user has provided false information regarding their age, we reserve the right to suspend or terminate the user’s account and delete any associated data.
Siso strongly encourages parents or guardians to actively monitor their children’s use of the app and ensure that their children comply with our age requirements. We recommend that parents use available tools to limit the collection of personal information from minors and supervise their children's online activities to protect their privacy.
Parents and guardians should be aware that, while Siso takes measures to restrict access to minors, we cannot control all interactions and user-generated content within the app. We advise that parents and guardians review the app’s content and features to understand how their children may interact with the platform.
If we discover that we have inadvertently collected personal data from a user under the age of 18, we will immediately take action to delete the data and terminate the user’s account. This action will be taken as soon as we are made aware of such a situation, either through user reports or our own internal checks.
If you believe we have collected information from a child under the age of 18, or if you are a parent or guardian and wish to request the deletion of data related to your child, please contact us immediately at service@siso.social
Siso is committed to complying with all relevant laws and regulations regarding the protection of children's privacy, including the Children’s Online Privacy Protection Act (COPPA) in the United States and similar laws in other countries. We follow these laws strictly to ensure that minors' privacy is respected and protected.
We take user safety seriously and have put several measures in place to promote a safe online environment. However, parents and guardians should understand that while we strive to create a protected environment for all users, we cannot guarantee the safety of minors when interacting with other users.
We encourage parents to have discussions with their children about online safety, including responsible use of apps, protecting personal information, and interacting with others online.
We value your privacy and will only share your personal information under specific and limited circumstances. We do not sell your personal data to third parties. The following outlines how and when your information may be shared:
5.1 Public Information
If you choose to make certain fitness-related data (such as achievements, workout records, or fitness plans) public, this information may be visible to other users of Siso. The visibility of this data depends on your privacy settings, which you can manage in the app under [privacy preferences section]. Please be aware that any information you choose to disclose publicly becomes accessible to others and can be collected or used by them.
5.2 Third-Party Services and Partners
We may share limited and necessary data with trusted third-party partners such as:
• Fitness equipment manufacturers,
• Health insurance providers,
• Analytics service providers,
• Cloud infrastructure vendors.
Such data sharing will only occur with your explicit consent and for clearly defined purposes (e.g., syncing device data, providing extended fitness benefits, or offering incentives). We will always inform you of the type of information being shared, the partner involved, and the intended use case.
All third-party partners are contractually bound to maintain confidentiality and comply with applicable data protection regulations.
5.3 Legal Compliance and Enforcement
We may disclose your personal information when required to do so by law, legal process, or court order. This includes:
• Responding to legal claims,
• Complying with judicial or administrative proceedings,
• Cooperating with law enforcement authorities or regulatory agencies.
We will make such disclosures only when legally obligated and will notify you when permitted by law.
Applicable Law: [The laws in your area]
We take the security of your personal information seriously and have implemented comprehensive measures to protect it from unauthorized access, disclosure, alteration, or destruction. All sensitive data—including health information, activity records, and payment details—is encrypted both in transit and at rest using industry-standard protocols.
Only authorized personnel with clearly defined responsibilities are granted access to your personal data, and their access is restricted through role-based permissions. We maintain internal policies and conduct regular audits to ensure data is handled securely and ethically.
To ensure the continuity and integrity of your fitness experience, user data is routinely backed up. In the event of system malfunctions, service disruptions, or unexpected data loss, these backups allow us to restore core user information efficiently.
Our security infrastructure is continually reviewed and updated to adapt to emerging threats and evolving best practices in data protection. However, no system can be guaranteed 100% secure. Should a security breach occur that is likely to result in a high risk to your rights or freedoms, we will notify you in accordance with applicable legal requirements.
At Siso, we believe users should have full transparency and control over their personal data. You can manage your privacy settings directly within the app to determine whether your fitness data—such as activity records, workout performance, or personal goals—is visible to other users or kept private. These settings allow you to customize what you share and with whom, helping you maintain your desired level of privacy throughout your fitness journey.
In addition, you have complete control over your location permissions. You may choose to enable location access, for example, to track your outdoor runs using GPS, or you may disable it entirely through your device settings or within the app. If disabled, features dependent on location data may be limited, but your overall access to core functionality will not be affected.
You can also manage the types of notifications you receive. Whether it's workout reminders, daily summaries, or promotional offers, you have the right to opt in or out at any time via your settings. Siso respects your preferences and will only send notifications relevant to your selected interests and goals.
Most importantly, we provide tools that allow you to access, correct, update, or permanently deleteyour personal information and fitness history. If you decide to stop using the app, you may delete your account and request full data erasure. Such actions can be performed through the app or by contacting us at service@siso.social
Siso is committed to empowering users with clear and actionable rights regarding their personal data, in compliance with applicable law and global data protection standards. As a user of Siso, you are entitled to a range of data rights that help you stay informed and in control.
You have the right to access and correct your personal information stored in the app. If any of your health or fitness data is inaccurate or outdated, you may request corrections through in-app tools or by contacting service@siso.social
You also have the right to request deletion of your personal data, including fitness records that are no longer necessary for the purposes for which they were collected. Upon verification, we will securely remove your information unless legal obligations require us to retain certain data for a specified period.
In addition, you are entitled to data portability, meaning you may request a copy of your fitness data in a structured, commonly used format so that it can be transferred to another service or platform of your choice.
Furthermore, you have the right to withdraw consent at any time. If you previously allowed us to collect specific types of data—such as location, biometric inputs, or enhanced tracking—you may revoke this permission and we will cease further processing of that information. Withdrawal of consent does not affect the legality of prior data processing based on your initial agreement.
To exercise any of these rights or to obtain more information, please contact us at service@siso.social We will respond to verified requests within the timeframes required by applicable law.
Siso is committed to safeguarding the personal information of minors and adheres to applicable law in establishing clear data protection mechanisms to prevent the collection and misuse of data from individuals under the age of 18.
9.1 No Registration by Minors
Siso’s services and content are not intended for individuals under 18 years of age. We do not knowingly permit minors to register accounts or access core functionalities. An age verification process is in place during registration. If it is discovered that a minor has created an account or is using the service, we will immediately terminate the account and delete all associated data.
9.2 No Active Collection of Minor Data
Siso does not knowingly or intentionally collect personal data from minors, including but not limited to identity information, fitness logs, location data, payment details, or social interactions. All data collection mechanisms are designed for adult users and include safeguards to prevent the accidental collection of minor data.
9.3 Parental Oversight Encouraged
We strongly recommend that parents and legal guardians actively monitor their children's use of digital devices and applications. Setting appropriate access restrictions is essential to prevent exposure to age-inappropriate content. If you suspect that your child has used Siso without proper authorization, please contact us immediately so we can restrict access and remove data as needed.
9.4 Special Protections for Inadvertently Collected Data
If any minor’s data is inadvertently collected due to legal exceptions or technical errors, Siso will only process such data after obtaining explicit parental or legal guardian consent and in accordance with the principle of data minimization. Additional protective measures will include:
• Prohibiting use for advertising, profiling, or analytics;
• Restricting access to specially authorized personnel only;
• Ensuring no sharing or sale of data to third parties;
• Encrypting all stored data with minimal retention duration.
9.5 Parental Deletion Requests
Parents or guardians who believe their child has submitted personal data to Siso may contact us at service@siso.social to request data deletion. Upon verification of identity and parental relationship, and in accordance with applicable law, we will:
• Delete the child’s account and all related data;
• Block future registrations from the same device;
• Notify the guardian via email once the deletion is completed.
Under applicable data protection laws, certain types of personal data are classified as sensitive personal information, and are subject to enhanced security and compliance requirements. While using the Siso app, we may collect or process the following categories of sensitive data in specific circumstances:
• Health and Fitness Information: Including but not limited to your weight, height, BMI, heart rate, workout intensity, training plans, and fitness performance;
• Precise Geolocation Data: Such as GPS-tracked routes, outdoor activity paths, or location-based check-ins;
• Social Interaction Information: If you link your account to a third-party platform, this may include your friends list, group participation, public comments, and interaction history.
Siso adheres to the principles of data minimization and informed consent, and only collects and processes sensitive information when it is strictly necessary for core fitness functions or with your explicit authorization. We implement the following measures to ensure the special protection of such data:
1 Separate and Explicit Consent: We will inform you clearly—via a dedicated interface—of the type, purpose, and potential risks of processing sensitive data, and will only proceed with your explicit consent;
2 Advanced Encryption and Access Control: All sensitive data is protected through industry-standard encryption during storage and transmission, and access is limited via role-based permissions;
3 Purpose Limitation: Sensitive data is used solely for personalized training, fitness assessments, and related services. It will not be used beyond the stated purposes or shared without your approval;
4 User Rights and Control: You may access, correct, delete, or withdraw your consent to the use of sensitive information at any time via the app settings or by contacting us at service@siso.social
Before providing any sensitive personal information, we encourage you to review all consent prompts carefully. If you have questions regarding how your sensitive data is processed, feel free to contact us. Siso is committed to fulfilling its legal obligations and safeguarding your privacy and data security.
We retain your personal and fitness-related data only for as long as it is necessary to fulfill the purposes outlined in this Privacy Policy, and for the duration of your active use of the Siso app. Your workout records, health metrics, profile information, and preferences are stored while your account remains active and will be securely deleted upon your request to close your account.
You have the right to request the permanent deletion of your account and all associated personal data. Upon such request, and after verifying your identity, we will erase your data from our primary systems unless retention is required by law—for example, in cases of unresolved disputes, fraud prevention, or compliance with applicable law.
Please note that some data may remain in encrypted backup archives for a limited time even after deletion. This is due to our disaster recovery, business continuity, and legal compliance protocols. Such backup data is not used for any active processing and will be deleted on a rolling basis in accordance with our internal retention schedules.
If you have any questions about data retention or wish to initiate deletion, please contact us at service@siso.social
