Privacy Policy
Last updated: 5 May 2026
1. Introduction
Vennio ("we," "us," or "our") is a demand-side scheduling infrastructure platform that helps businesses and individuals coordinate meetings by aggregating calendar availability. This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our service at vennio.app.
We are committed to protecting your privacy and handling your data transparently. Please read this policy carefully to understand our practices regarding your personal data.
2. Data Controller
For the purposes of UK GDPR and EU GDPR, the data controller is:
Whisker One Ltd (trading as Vennio)
Company number: 16270781
Registered office: 34 The Broadway, North Shields NE30 2LQ
Email: matt@vennio.app
Website: https://vennio.app
3. Information We Collect
3.1 Account Information
When you create an account, we collect:
- Name: Your full name as provided by your authentication provider
- Email address: Used for account identification and communications
- Profile picture: If provided by your authentication provider (optional)
- Authentication tokens: Encrypted OAuth tokens to maintain your calendar connections
You may authenticate using Google OAuth or Microsoft OAuth.
3.2 Calendar Data
With your explicit permission, we access calendar data from your connected accounts.
What we read and store:
- Free/busy status (available, busy, tentative)
- Event start and end times
- Calendar timezone settings
- The list of calendars in your connected account (so you can choose which calendar Vennio uses)
What we do not read or store:
- Event titles or descriptions
- Attendee lists or email addresses
- Event locations
- Meeting notes or attachments
- Private or sensitive event details
The OAuth scopes we request technically permit access to event titles, attendees, descriptions, and locations. In line with Google's Limited Use requirements and our own data minimisation principles, Vennio reads and stores only the timing and free/busy fields listed above. We do not read, store, log, or transmit event content fields, even when the API returns them.
The only exception is when Vennio creates a calendar event on your behalf in response to a confirmed booking. In that case, we write a title (e.g. "Meeting with [customer name]"), the booking time, and the customer's email address as an attendee. We do not modify any of your existing events.
If additional calendar permissions are required for specific features in future, we will clearly explain what data is needed and request your explicit consent before accessing it.
3.3 Scheduling Data
When you use our scheduling features, we collect:
- Proposed meeting times and responses
- Scheduling preferences and settings
- Booking confirmations and history
- Communications related to scheduling
3.4 Usage Data
We automatically collect certain information when you use the Service:
- Pages and features accessed
- Time spent on the Service
- Actions taken (clicks, form submissions)
- Device information (browser type, operating system)
- IP address (anonymised for analytics)
- Referring website or source
3.5 Communications Data
When you contact us, we collect:
- Email correspondence

4. How We Use Your Information

We will never use your calendar data to:

5. Google API Services Disclosure
Vennio'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.
We request the following Google OAuth scopes:
- https://www.googleapis.com/auth/calendar.events — used to read event start and end times for availability calculation, to create calendar events when bookings are confirmed (with the booker added as an attendee), and to register webhooks that notify Vennio of changes to your calendar so availability stays accurate. We do not read or store event titles, descriptions, attendees of your existing events, or event locations.
- https://www.googleapis.com/auth/calendar.calendarlist.readonly — used to display the list of your calendars so you can choose which one Vennio reads availability from and writes booking events to.
- openid, email, profile — used to identify your Vennio account and display your name and email in the application.
We do not request access to your full Google Calendar, the ability to share or modify calendars themselves, or any scope outside the list above.
Specifically, we confirm that:
- Limited Use: We only use Google user data to provide and improve the scheduling features you have requested. We do not use Google user data to serve advertisements, build advertising profiles, or train machine learning models unrelated to providing the Service.
- No unauthorised sharing: We do not transfer Google user data to third parties except:
- As necessary to provide the Service (for example, infrastructure providers listed in Section 7.2)
- With your explicit consent
- As required by law
- In connection with a merger, acquisition, or sale of assets, with notice to you
- No human access without consent: We do not allow humans to read your Google user data unless:
- You have given us affirmative agreement for specific messages (for example, when you submit a support request that references your calendar)
- It is necessary for security purposes (for example, investigating abuse or a security incident)
- It is required to comply with applicable law
- The data has been aggregated and anonymised, and is being used for internal operations
- Security: We implement appropriate security measures to protect Google user data from unauthorised access, alteration, disclosure, or destruction. OAuth tokens are encrypted at rest using AES-256-GCM. Access controls and authentication apply to all systems handling Google user data.
6. Microsoft API Services Disclosure
When you connect a Microsoft account, we access your calendar data through the Microsoft Graph API. We request the Calendars.ReadWrite scope to read your calendar events for availability calculation and create events when bookings are confirmed. We comply with Microsoft's API Terms of Use and the Microsoft Privacy Statement.
We apply the same data minimisation and security principles to Microsoft data as we do to Google data, as described in this Privacy Policy.
7. Data Sharing
We do not sell, rent, or trade your personal information.
We share your data only in the following circumstances:
7.1 With Your Consent
- Availability sharing: We display your free/busy times to parties you explicitly choose to share with through the Service
