Privacy Policy

Last updated: 5 October 2026

1. Introduction

Nynch ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our platform and services.

As a UK-based company serving customers worldwide, we comply with the UK General Data Protection Regulation (UK GDPR), the EU General Data Protection Regulation (EU GDPR), and other applicable data protection laws. We are the data controller responsible for your personal data.

2. Information We Collect

2.1 Personal Data You Provide

We collect personal data that you voluntarily provide when you:

  • Register for an account (name, email address, company name, job title)
  • Subscribe to our services (billing information, payment details)
  • Contact us for support (correspondence and contact details)
  • Use our platform features (contact information, relationship data, activity logs, campaign information)
  • Participate in surveys or provide feedback
  • Request a free resource from our website, such as a guide or the relationship capital workbook (email address, optional first name, and any answers and numbers you entered in the calculator). To have these deleted, email privacy@nynch.com.

2.2 Automatically Collected Information

  • Device information (IP address, browser type, operating system)
  • Usage data (pages visited, features used, time spent on pages)
  • Log data (access times, error logs, performance data)
  • Cookies and similar tracking technologies

2.3 Information from Third Parties

  • LinkedIn profile information you save using the Nynch browser extension (see section 3)
  • Calendar services (for scheduling and time-blocking features)
  • Email services (for unified inbox functionality)
  • Payment processors (for billing and subscription management)

3. Nynch Browser Extension

The Nynch Relationship Assistant browser extension is optional. If you install it, it works only while you are viewing a LinkedIn profile page, and only when you actively use it.

3.1 What the extension collects

When you open the Nynch side panel on a LinkedIn profile, or press Save, the extension reads the information displayed on that profile (name, headline, job title, company, location and profile URL) and sends it to Nynch so we can show you your existing record for that person, or create one at your request.

The extension also stores your Nynch sign-in session locally in your browser so it can access your own Nynch workspace. It never asks for, sees, or stores your LinkedIn password, and it never asks for your Nynch password.

3.2 What the extension does not do

  • It does not collect your LinkedIn connections, search results, feed, or messages.
  • It does not read any page other than the profile you are actively viewing.
  • It does not read LinkedIn network traffic.
  • It does not run in the background, and does nothing unless you ask it to.
  • It takes no action on LinkedIn on your behalf: it sends no messages, posts no comments, and sends no connection requests.
  • It contains no advertising, analytics, or third-party services of any kind.

3.3 Removing the extension

You can remove the extension at any time from your browser's extensions page. Removing it deletes the stored sign-in session from your browser immediately. Information already saved to your Nynch workspace is handled under the rest of this policy, including your rights in section 10.

3.4 Chrome Web Store Limited Use

Nynch's use and transfer of information collected by the Nynch Relationship Assistant extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. We use this information only to provide the extension's single purpose. We do not sell it, we do not use or transfer it for personalised advertising, and we do not use or transfer it to determine creditworthiness or for lending purposes.

3.5 Not affiliated with LinkedIn

Nynch is an independent product. It is not affiliated with, endorsed by, or sponsored by LinkedIn or Microsoft.

4. Google Account Data

This section explains how Nynch handles information it receives from Google APIs when you sign in with Google or connect your Gmail, Google Calendar or Google Docs account. Connecting these services is optional, and you choose which to connect.

4.1 What we access

  • Google sign-in: your name, email address and profile picture, used to create and sign in to your Nynch account.
  • Gmail (read): the messages in the Gmail account you connect, including senders, recipients, subjects, dates and message content, so Nynch can show your email history with each contact and keep your relationship records up to date.
  • Gmail (send): permission to send emails that you write or approve in Nynch from your own Gmail address.
  • Gmail (modify): permission to move a message to Gmail Trash when you choose to delete it in Nynch, for example when you block a sender.
  • Gmail settings (read only): your Gmail "Send mail as" addresses, so you can choose which of your own addresses an email is sent from. We do not change your Gmail settings.
  • Google Calendar: your calendar list and events, so Nynch can show your meetings against your contacts, and create or update events when you ask it to, for example scheduling a meeting or adding meeting preparation notes to an event.
  • Google Docs: permission to create a new Google Doc when you choose to export a proposal from Nynch.

4.2 How we use it

We use Google user data only to provide and improve the user-facing features you see in Nynch: your contact and relationship history, reminders, meeting preparation, drafting and sending emails, and proposal export. Some of these features use artificial intelligence. To provide them, relevant email and calendar content is sent to our AI service providers (OpenAI, Anthropic and Google) through their business APIs, solely to generate the result you see, such as a summary, a suggested follow-up or a draft reply. Nothing is sent from your Gmail account without your action or approval.

4.3 What we do not do

  • We do not sell Google user data.
  • We do not use or transfer Google user data for advertising, including personalised, retargeted or interest-based advertising.
  • We do not use or transfer Google user data to determine creditworthiness or for lending purposes.
  • We do not use Google user data to develop, improve or train generalised or non-personalised AI or machine learning models.
  • Nobody at Nynch reads your Google user data unless you give us explicit permission for specific messages (for example, when you ask for support), it is necessary for security purposes such as investigating abuse, it is required to comply with the law, or the data has been aggregated and anonymised for internal operations.

4.4 Storage and sharing

Emails and calendar events synced from your Google account, and the access tokens that let Nynch connect to it, are stored in our database hosted by our infrastructure provider (Supabase), protected by access controls and encrypted in transit. We share Google user data only with the service providers needed to run the features described above (our hosting provider and our AI service providers), when required by law, or as part of a merger or acquisition with your data remaining subject to this policy.

4.5 Retention and deletion

You can disconnect your Google account at any time in Nynch or from your Google Account permissions page. When you disconnect in Nynch, we revoke our access with Google and stop syncing. Emails and calendar events already synced remain in your Nynch workspace as part of your relationship history until you ask us to delete them. To delete your synced Google data or your whole account, email privacy@nynch.com and we will delete it within one month, as data protection law requires, except where we must keep information to comply with the law.

4.6 Google API Services User Data Policy

Nynch's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

5. How We Use Your Information

  • Service Delivery: To provide, maintain, and improve our platform
  • Account Management: To create and manage your account and provide support
  • Billing and Payments: To process transactions and send invoices
  • Communication: To send service-related notifications and marketing (with consent)
  • Analytics and Improvement: To understand how users interact with our services
  • Security: To monitor and prevent fraud, abuse, and security incidents
  • Legal Compliance: To comply with legal obligations and enforce our terms
  • AI Features: To power intelligent features such as relationship insights and campaign optimisation

6. Legal Basis for Processing (UK/EU GDPR)

  • Contract Performance: Processing necessary to provide our services
  • Legitimate Interests: Improving our services, analytics, and fraud prevention
  • Legal Obligation: Processing required by law or regulation
  • Consent: Where you have given explicit consent for specific processing

7. Data Sharing and Disclosure

We do not sell your personal data. We may share your information with trusted service providers (hosting, payments, analytics, support), in connection with business transfers, or when required by law. We may also share with your explicit consent.

8. International Data Transfers

When transferring data internationally, we use Standard Contractual Clauses, adequacy decisions, or other approved mechanisms under UK and EU GDPR.

9. Data Retention

  • Account data: retained while active and up to 12 months after closure
  • Transaction records: retained for 7 years for tax compliance
  • Usage data and logs: up to 24 months
  • Marketing consent records: until you withdraw consent

10. Your Data Protection Rights

  • Right of Access: Request a copy of your personal data
  • Right to Rectification: Request correction of inaccurate data
  • Right to Erasure: Request deletion (subject to legal obligations)
  • Right to Restrict Processing: Request limitation on how we use your data
  • Right to Data Portability: Receive your data in machine-readable format
  • Right to Object: Object to processing based on legitimate interests
  • Right to Withdraw Consent: Withdraw consent at any time

To exercise any of these rights, contact us at privacy@nynch.com.

11. Data Security

We implement encryption in transit and at rest, regular security assessments, access controls, employee training, incident response procedures, and regular backups. No method of transmission is 100% secure.

12. Cookies

We use cookies and tracking technologies to enhance your experience and analyse usage. See our Cookie Policy for details.
