This Privacy Policy describes how Sumidata.io ("we", "us", or "our") collects, uses, and shares information when you use our session replay and analytics service.
We act as a controller for account, billing, and our own service usage data. For personal data collected through your use of the Service, we act as your processor under our Data Processing Agreement.
When you create an account, we collect:
When you install our SDK on your website, we collect data from your end users' sessions, including:
IP addresses are collected and stored together with session, event, and log records. We use them for security, abuse and fraud prevention, diagnostics, and to derive an approximate location. IP addresses are retained for the same period as the rest of your session recording data (see Section 5) and are removed by account deletion and by on-request erasure.
We automatically collect information about how you use the Sumidata dashboard:
If you turn on the site chat widget on your website, we collect what your end users send through it and what your team replies:
An end user's email address is used only to tell them that your team has replied in their conversation. Chat messages, images and email addresses are kept for up to 3 years from the conversation's last message (see Section 5) and are deleted earlier, images included, when you delete the conversation in the dashboard.
Sumidata is designed with privacy as a core principle. Our SDK includes:
Input masking applies to form fields in recordings. Page text, console logs, and network data may still contain personal information. Network capture filters common credential fields and can be configured to omit request and response bodies; these safeguards do not replace reviewing the data your website sends.
We use the collected information to:
We share your information with the following sub-processors and parties:
When you use AI Analyst, Anthropic processes your conversation, project context, and query results from your project data to answer your questions. This may include personal data present in those inputs or results. For AI-powered site analysis, Google Gemini processes the page URL and technical information about the site. These providers support the respective AI features of the Service.
We do not sell your personal information or the data collected from your end users.
Session recording data is stored for up to 3 years from the date of collection, and the full 3-year history is viewable and queryable in the dashboard on every plan, including Free. Data older than 3 years is permanently deleted. You can request earlier deletion of your project's data at any time by contacting support@mail.sumidata.io; deletion requests are honored regardless of your plan.
If you cancel your subscription, your workspace moves to the Free plan: your data stays stored — and remains accessible — under the same 3-year retention period. You can request deletion of your data at any time, as described above.
Account information is retained for as long as your account is active and for a reasonable period thereafter for legal and business purposes.
Invoices and payment records are retained for a longer period as required to comply with our legal, accounting, and tax obligations, even after your account is deleted.
Our SDK does not use cookies. Instead, it stores identifiers in the browser's storage on your website:
These identifiers do not track end users across different websites and are not used for advertising. Because the device identifier persists across visits, it may require end-user consent in some jurisdictions (such as under EU ePrivacy rules) in the same way cookies do; obtaining any required consent is your responsibility as the website owner.
The Sumidata dashboard stores authentication tokens in your browser's local storage and does not use advertising cookies.
Depending on your location, you may have the following rights:
To exercise these rights, contact us at support@mail.sumidata.io.
As a Sumidata customer, you are responsible for:
We implement appropriate technical and organizational measures to protect your data, including:
Your data may be processed in countries outside your own. We ensure appropriate safeguards are in place for any international transfers, including standard contractual clauses where required.
The Service is not intended for children under 18. We do not knowingly collect personal information from children. If you believe we have collected information from a child, please contact us.
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy and updating the "Last updated" date. Your continued use of the Service constitutes acceptance of the updated policy.
