2.6 User-Provided Session Data (BYOS)
When you use our Bring Your Own Session (BYOS) authenticated scraping feature, you may provide us with third-party session data to enable scraping of authenticated content. This data may include:
- Session cookies from third-party websites (e.g., authentication tokens, login session identifiers)
- Authentication headers or bearer tokens you provide via the API
- Cookies captured through the AlterLab Chrome Extension cookie capture feature
- Domain associations for stored session data (which websites the cookies belong to)
Important: We treat all user-provided session data as highly sensitive authentication material. You are responsible for ensuring you have the right to use and share the session data you provide. We do not access, read, or use your session cookies for any purpose other than injecting them into your authorized scraping requests.
3. How We Use Your Information
We use the information we collect for the following purposes:
- Service Provision: To provide, maintain, and improve our web scraping API service, including processing your API requests and delivering results
- Account Management: To create and manage your account, authenticate users, and provide customer support
- Billing and Payments: To process payments, manage subscriptions, track usage, and send invoices
- Communication: To send you service updates, security alerts, technical notices, and responses to your inquiries
- Analytics and Improvement: To analyze usage patterns, identify trends, and improve our Service's performance and features
- Security: To detect, prevent, and address technical issues, fraud, and unauthorized access
- Compliance: To comply with legal obligations, enforce our Terms of Service, and protect our rights and property
- Marketing: With your consent, to send promotional materials, product announcements, and newsletters (you may opt-out at any time)
- Research and Development: To develop new features, services, and technologies
- Authenticated Scraping (BYOS): To inject your user-provided session cookies and authentication tokens into scraping requests on your behalf, enabling access to authenticated content on third-party websites
3.1 Legal Basis for Processing (GDPR Article 6)
For users in the European Economic Area (EEA) and the United Kingdom, we process your personal data on the following legal bases:
- Contractual Necessity (Art. 6(1)(b)): Processing necessary to perform our contract with you, including account creation, service provision, API request processing, billing, and customer support.
- Legitimate Interests (Art. 6(1)(f)): Processing necessary for our legitimate interests, including fraud prevention, service security, analytics and service improvement, and internal administration. We balance these interests against your rights and freedoms.
- Legal Obligation (Art. 6(1)(c)): Processing necessary to comply with legal obligations, including tax and accounting requirements, responding to lawful government requests, and data breach notification obligations.
- Consent (Art. 6(1)(a)): Where we rely on your consent, such as for marketing communications and optional analytics cookies, you may withdraw consent at any time without affecting the lawfulness of processing carried out before withdrawal.
4. Data Storage and Security
We implement industry-standard security measures to protect your personal information from unauthorized access, disclosure, alteration, and destruction. Our security practices include:
- Encryption of data in transit using TLS/SSL protocols
- Encryption of sensitive data at rest using AES-256 encryption
- Secure API key storage using Argon2 hashing algorithms
- Regular security audits and vulnerability assessments
- Access controls and authentication mechanisms
- Monitoring and logging of security events
- Regular backup procedures with encrypted storage
- Incident response procedures and breach notification protocols
Your data is stored on secure servers located in the United States. We use reputable cloud infrastructure providers that comply with industry security standards and certifications.
4.1 BYOS Session Data Security
User-provided session data receives additional security protections due to its sensitive nature:
- Encryption at rest: All stored session cookies are encrypted using AES-256-GCM with per-user encryption keys
- Domain isolation: Session data is strictly scoped to the domain it was provided for and cannot be used across different domains
- Inline mode (memory-only): When session cookies are passed directly in an API request (inline mode), they are held in memory only for the duration of that request and are never persisted to disk or database
- Access control: Only the account that created a stored session can access or use it — session data is never shared between accounts
- Transport security: All session data is transmitted exclusively over TLS-encrypted connections
While we strive to protect your personal information, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security, but we continuously work to improve our security practices.
6. Your Rights and Choices
Depending on your location, you may have certain rights regarding your personal information under applicable data protection laws, including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
6.1 Right to Access
You have the right to request access to the personal information we hold about you. We will provide you with a copy of your data in a structured, commonly used, and machine-readable format.
6.2 Right to Rectification
You have the right to request that we correct any inaccurate or incomplete personal information we hold about you. You can update most information directly through your account settings.
6.3 Right to Deletion
You have the right to request deletion of your personal information, subject to certain exceptions (e.g., legal obligations, fraud prevention, or legitimate business purposes). You can delete your account at any time through your account settings.
6.4 Right to Data Portability
You have the right to request a copy of your personal information in a portable format that can be transferred to another service provider.
6.5 Right to Opt-Out

While we encourage you to contact us first to resolve any concerns, this right can be exercised at any time.
To exercise any of these rights, please contact us at [email protected]. We will respond to your request within 30 days.
8. BYOS Session Data Handling
This section describes how we handle session data you provide through our Bring Your Own Session (BYOS) authenticated scraping feature, including cookies submitted via the API and those captured using the AlterLab Chrome Extension.
8.1 What We Collect and Store
- Stored sessions: When you create a named session via the API or Chrome Extension, we store the encrypted cookie data, the associated domain, a user-defined session name, and metadata (creation date, last used date)
- Inline sessions: When you pass cookies directly in an API request, we process them in memory only — no cookie data is written to disk or persisted after the request completes
- Chrome Extension capture: The AlterLab Chrome Extension reads cookies from your browser for domains you explicitly select and transmits them to our API over an encrypted connection. The extension does not capture cookies without your explicit action
8.2 How We Use BYOS Data
We use your session data solely to inject it into scraping requests you initiate. We do not analyze, profile, or extract information from your session cookies. We do not use your session data to access third-party accounts except as directed by your API requests.
8.3 Retention and Deletion
- Stored sessions: Retained until you explicitly delete them through the API or dashboard, or until your account is deleted. There is no automatic expiration — you maintain full control over the lifecycle of your stored sessions
- Inline sessions: Discarded immediately after the API request completes. No data is retained
- Account deletion: When you delete your account, all stored session data is permanently and irreversibly deleted within 30 days
8.4 Your Rights Over BYOS Data
In addition to the general rights described in Section 6, you have the following specific rights over your BYOS session data:
- View: You can list all stored sessions and their metadata (domain, name, creation date) via the API or dashboard at any time
- Delete: You can delete any individual session or all sessions at any time through the API or dashboard. Deletion is immediate and irreversible
- Export: You may request an export of your stored session metadata (excluding the encrypted cookie values) as part of a data portability request
8.5 Third-Party Responsibility
AlterLab acts as a data processor for BYOS session data that you provide. You are the data controller and are responsible for ensuring that your use of third-party session cookies complies with the terms of service of those third-party websites and all applicable laws. We do not verify the validity, ownership, or authorization of session data you provide.
9. Data Retention
We retain your personal information for as long as necessary to provide our Service, comply with legal obligations, resolve disputes, and enforce our agreements. Specific retention periods include:
- Account Information: Retained while your account is active and for up to 90 days after account deletion
- API Request Logs: Retained for 30 days for performance monitoring and debugging purposes
- Billing Records: Retained for 7 years to comply with tax and accounting regulations
- Support Communications: Retained for 3 years for quality assurance and legal purposes
- Analytics Data: Aggregated and anonymized data may be retained indefinitely for statistical analysis
- BYOS Session Data: Stored sessions are retained until you delete them or your account is deleted. Inline session cookies are discarded immediately after request completion. See Section 8 for full details
When we no longer need your personal information, we will securely delete or anonymize it in accordance with our data retention policies and applicable law.
10. International Data Transfers
Your information may be transferred to and processed in countries other than your country of residence. These countries may have data protection laws that are different from the laws of your country.
We are based in the United States, and our servers are located in the United States. If you are accessing our Service from outside the United States, please be aware that your information may be transferred to, stored, and processed in the United States.
We take appropriate measures to ensure that your personal information receives an adequate level of protection in accordance with applicable data protection laws. For transfers from the European Economic Area (EEA), we rely on standard contractual clauses approved by the European Commission. For details on our data processing commitments when we act as a processor on your behalf, see our Data Processing Agreement.
11. Children's Privacy
Our Service is not intended for children under the age of 18. We do not knowingly collect personal information from children under 18. If you are a parent or guardian and believe that your child has provided us with personal information, please contact us immediately.
If we become aware that we have collected personal information from children without verification of parental consent, we will take steps to remove that information from our servers.
12. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. We will notify you of any material changes by:
- Posting the updated Privacy Policy on this page with a new "Last updated" date
- Sending you an email notification to the address associated with your account
