Privacy Policy

Last updated: 3 November 2026

This policy explains what information designedbykoda collects, how it is used, and the choices you have, specifically in relation to the E-Ink Calendar product and its connection to your Google Calendar and, if you choose to use the To-do layout, your Google Tasks. If you have questions after reading this, contact us at hello@designedbykoda.com.

Information We Collect

When you connect your Google account to set up an E-Ink Calendar device, we collect:

• Your Google account email address and a unique account identifier, used to identify your account.
• Read only access to the Google Calendar or calendars you choose to connect, including event titles, start times, and whether an event is marked as an all day event.
• A device identifier and a device authentication credential, generated by your physical device during setup.
• Basic device settings you configure, such as your timezone and how often the device should refresh.
• Optional display settings you choose, such as the location used for weather, sunrise, sunset and moon times, the name and date for a Countdown, and a picture you upload for the Photo frame layout. An uploaded picture is converted to a small black and white image in your browser, and only that converted image is stored.

If you choose the To-do layout, you are asked separately to grant read only access to your Google Tasks. This is only requested at that point, not when you first connect your calendar. When your device refreshes, our server reads the titles, due dates and completion status of the tasks in your default Google Tasks list so they can be drawn on the screen. Your tasks are not saved in our database; they are used to build the screen image and then discarded.

If you vote in a poll on this site, we store your choices together with a random identifier saved in a cookie in your browser, and a one-way hash (it cannot be reversed) of your network address and browser type. These are used only so that voting again replaces your earlier vote instead of counting twice. Your name, email and address are not stored with your vote.

We do not request or receive access to any other Google service. We do not request permission to create, edit, or delete anything in your calendar or your tasks. All access is read only. Marking a task as done is done in Google Tasks or Google Calendar, not through our service.

How We Use This Information

The information above is used for one purpose: to let your physical E-Ink Calendar device retrieve your upcoming events (and, if you choose the To-do layout, your tasks) and display them on its screen. Specifically:

• Your Google account identifier links your device to your calendar selection.
• Your calendar data, and your task data if you use the To-do layout, is fetched by our server and passed to your device in a simplified format it can render.
• Your timezone setting is used to correctly calculate what day it is for you and when your device should refresh.

We do not use your data for advertising, do not build behavioural profiles from it, and do not sell it to any third party.

Our use and transfer of information received from Google APIs, including Google Calendar and Google Tasks, adheres to the Google API Services User Data Policy, including the Limited Use requirements. Data from Google is used only to provide the display feature described above. It is not used to develop, improve or train generalised AI or machine learning models, and no person at designedbykoda reads your calendar events or tasks, except where you ask us for support and give permission, or where the law requires it.

Data Storage and Security

We take the following specific steps to protect your data:

• The refresh token that grants access to your Google Calendar and Google Tasks is encrypted before it is stored. It is never stored in plain text.
• Your device's authentication credential is never stored directly. Only a one way cryptographic hash of it is kept, so the original value cannot be recovered even if our database were accessed.
• All data is stored using Cloudflare's infrastructure, and all communication between your device, your browser, and our servers happens over encrypted connections.

Third Party Services

To operate the E-Ink Calendar, we rely on a small number of service providers:

• Google, to authenticate your account and retrieve your calendar and task data. Google's own privacy policy applies to how they handle your account information.
• Cloudflare, which hosts our website, database, and server infrastructure.

If you join a waitlist for one of our products, your email address is stored with Brevo, our email service provider, solely to send you updates about that product.

Your Rights and Choices

You are in control of the access you grant us at all times:

• You can revoke our access to your Google Calendar and Google Tasks at any time from your own Google Account settings, at myaccount.google.com/permissions. This immediately stops us from being able to access your calendar or tasks.
• You can request that we delete your account and all associated data by contacting hello@designedbykoda.com.
• You can unsubscribe from any waitlist email using the link included in that email.

Data Retention

We retain your account information for as long as your device remains active and connected. If you delete your account or revoke access, we delete the associated encrypted refresh token and stop retrieving calendar and task data on your behalf. A picture uploaded for the Photo frame and any Countdown details are deleted with your account.

Children's Privacy

The E-Ink Calendar is not directed at children, and we do not knowingly collect information from anyone under the age of 13.

Changes to This Policy

If this policy changes, the updated version will be posted on this page with a revised date at the top.
