Synquil ("we", "us", or "our") operates the Synquil service (the "Service"). This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information. By using the Service, you agree to the collection and use of information in accordance with this policy.
Our role. For the business data you connect (section 1.4), you are the controller and Synquil is your processor: we handle it only to provide the Service, on your instructions. For your account, billing and usage information, Synquil is the controller.
When you sign up, we collect your name, email address, and profile picture via Clerk (our authentication provider). This information comes from your Google account or other sign-in method you choose.
When you connect a Google account, we request access to the following Google API scopes:
We store OAuth tokens for these scopes in our database, encrypted at rest using AES-256-GCM. These tokens are used solely to fetch data from the Google APIs on your behalf, at the sync frequency you have configured.
If you connect Notion or HubSpot, we similarly request the minimum OAuth scopes needed to read the data sources you select (databases, CRM objects, etc.). The same encryption and access controls apply.
The actual content of the spreadsheets, databases, or CRM records you select is fetched and stored in your private, isolated database schema, hosted in Frankfurt, Germany (AWS eu-central-1). This data is used exclusively to power the Synquil Service for your account. Synquil only reads from your sources and never writes to them.
We automatically collect:
We use strictly necessary cookies for sign-in (managed by Clerk) and remember your analytics choice in your browser. Product analytics (PostHog) stores nothing on your device and captures nothing until you choose "Allow" in the consent banner. To change your choice, clear this site's storage in your browser and the banner will ask again.
We do not use your Google user data, or any data from your connected sources, to train AI models — ours or anyone else's.
Synquil's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Specifically:
We do not sell, rent, or trade your personal information. We share data only in these limited circumstances:
We use the following sub-processors, who handle data solely to deliver the Service. The current list, with what each receives, is always at synquil.com/subprocessors, and we give 30 days' notice by email before adding one.
Each sub-processor is bound by a data processing agreement and handles data only as instructed.
We may disclose your information if required to do so by law or in good-faith belief that such action is necessary to comply with legal obligations, protect our rights, or prevent fraud.
In the event of a merger, acquisition, or sale of assets, your data may be transferred. We will provide notice before your data becomes subject to a different privacy policy.
We retain your account information and synced data for as long as your account is active. Cancelling a paid plan does not delete anything; your workspace returns to the Free plan. If you delete your account, all associated data — including OAuth tokens, synced data, schema definitions, roles, API keys and logs — is permanently deleted within 30 days (deletion from Settings takes effect immediately). Records deleted in a connected app are removed from our copy on the next sync. Billing records may be retained for up to 7 years as required by applicable law.
You can revoke Google access at any time via Google Account Permissions. Upon revocation, we will no longer be able to sync your Google Sheets data.
We implement the following security measures:
No method of transmission over the internet is 100% secure. While we strive to use commercially acceptable means to protect your data, we cannot guarantee its absolute security.
Depending on your jurisdiction, you may have the following rights regarding your personal data:
To exercise any of these rights, email us at hello@synquil.com. We will respond within 30 days. You may also delete your account directly from the Settings page, which initiates immediate data deletion. If you are in the EEA or UK, you may also complain to your local data protection authority.
US residents. Under California (CCPA/CPRA) and other US state privacy laws you have the rights to know, access, correct and delete your personal information and to opt out of its sale or sharing. We do not sell or share personal information for cross-context behavioural advertising, and we do not use it for profiling. We will not discriminate against you for exercising these rights.
Data in your connected sources. If someone whose data is in your connected tools asks us to act on it, we will refer them to you, as controller, and help you respond.
The Service is not directed at children under the age of 13 (or 16 in the European Economic Area). We do not knowingly collect personal information from children. If you believe we have inadvertently collected such information, please contact us immediately.
Customer data is stored in Frankfurt, Germany (AWS eu-central-1) and our application servers run in the Netherlands. Some sub-processors are in the United States (see section 4.1): the AI model, sign-in, billing, email and analytics. For transfers out of the EEA, UK or Switzerland we rely on the EU-US Data Privacy Framework where the recipient is certified, and on Standard Contractual Clauses otherwise.
We may update this Privacy Policy from time to time. We will notify you of material changes by emailing the address associated with your account at least 14 days before the change takes effect. The "Last updated" date at the top of this page will always reflect the most recent revision. Continued use of the Service after a change takes effect constitutes acceptance of the revised policy.
If you have questions, concerns, or requests regarding this Privacy Policy or your personal data, please contact us:
