Privacy Policy

Last updated 3 November 2026

Interval is a place for the things you need to do, remember, and come back to later. Some of that can be personal, so we want our privacy policy to be easy to understand.

Interval is a place for the things you need to do, remember, and come back to later. This policy explains how we handle your information and what choices you have. By continuing to use Interval, you agree to this Privacy Policy.

Your planner content is private by default. We don’t sell your personal information, share it with advertisers, or use what you write to train AI models. Interval doesn’t use third-party advertising trackers or build advertising profiles from your planner content.

Your account and planner data

Guest use. You can use Interval without an account. Your work stays on the device or browser where you created it. When you sign in, Interval imports your guest work into your account. Signing out hides your account content and returns you to separate guest storage.

Account information. When you sign in with Apple or Google, we may store your email address and the identifier the provider gives us. We use them to recognize and secure your account and keep your work connected to you.

Planner content. When you’re signed in, Interval’s systems store and sync your tasks, notes, plans, settings, and files automatically, without routine human review. If you publish an Interval page through a shared link, people with access to that link can see what you chose to publish.

Technical information. We may collect your device type, app version, and crash or error information to diagnose problems and make Interval more reliable.

Supabase provides authentication and stores account content and files. Vercel hosts the website and API. Cloudflare operates the gateway for connected Model Context Protocol (MCP) tools.

Product analytics and browser storage

We use PostHog to understand how people get started, which features they use, and where they run into trouble. That helps us make onboarding easier, fix problems, and improve the parts of Interval you use. We limit collection to usage information that helps us do that, such as interactions with onboarding, planner features, sign-in, and subscription screens.

Analytics events are pseudonymous. They use a random analytics ID so we can understand how people use Interval over time. On iPhone and iPad, that ID can be linked to your Interval account so we can recognize usage across sign-in and devices. We don’t send your email address, sign-in account ID, what you write in Interval, your search terms, or the contents of shared links to PostHog. PostHog receives your IP address as part of the request, and our project is configured to discard it from stored events.

Product analytics is on by default, with no in-app switch. On the web, Interval skips analytics if your browser sends a Do Not Track or Global Privacy Control signal. Authentication cookies keep you signed in, and local storage saves your work on your device or browser.

Email communications

If you sign in, we may email you Interval news, feature announcements, and product updates. You can unsubscribe using the link in any of those emails. You’ll keep access to Interval and your data, and we may still send necessary account, security, and service messages.

Calendar connections

Apple Calendar

If you connect Apple Calendar, Interval reads the calendar information needed to show your events alongside your plans. We use it to provide the calendar features you enable. You can remove access in your device settings at any time.

Google Calendar

Google Calendar sync is paused for launch, so Interval doesn’t fetch or display Google Calendar events right now. Google sign-in remains available. Previously stored encrypted authorization credentials may remain until you delete your Interval account. You can revoke access in your Google Account’s third-party connections settings.

When sync is available, Google Calendar is optional and requires its own permission. Interval reads your selected calendars and event titles, dates, times, and identifiers to show events alongside your plans on the web, iPhone, and iPad. Interval doesn’t create, edit, or delete Google Calendar events.

Vercel hosts the Calendar API and processes event responses and authorization tokens in transit and in server memory. Events are held temporarily in app memory and kept out of the task and note database. Supabase receives Google sign-in identity information when you choose Google sign-in. It also stores your Calendar connection status and encrypted access and refresh tokens. Google receives the requests needed to authorize the connection, refresh it, read events, or revoke access.

Calendar events are available only in your signed-in Interval app or browser. We don’t send Google Calendar events or credentials to PostHog, advertisers, connected MCP tools, or public Interval pages. We don’t sell Google user data or use it for advertising or AI training.

When sync is available, you can disconnect Google Calendar in Interval Settings. This removes the stored tokens and asks Google to revoke access. If Google can’t confirm revocation, Interval tells you, and you can revoke access in your Google Account settings. Deleting your Interval account also removes the stored connection.

Our use and transfer of information received from Google APIs follows the Google API Services User Data Policy, including its Limited Use requirements.

Tools you connect

You can authorize tools such as Cursor or Claude to work with parts of your planner through the Model Context Protocol (MCP). What they can access depends on the permissions you grant. You can revoke access at any time. Information you choose to share with a connected tool may be handled under that service’s privacy policy.

Security, retention, and deletion

We use encrypted connections to transmit your data and rely on the security protections of our hosting and database providers.

We keep account information and planner content while your account exists and we need the information to provide Interval. To delete your account, go to Settings → Delete account. After you confirm, Interval removes your account, planner content, files, shared links, and stored connected-service permissions from active systems promptly and signs you out. Backup copies may remain for up to 30 days as routine backups expire.

Your privacy choices and rights

You can contact us to request a copy of your personal data, correct your account information, or request deletion. Depending on where you live, you may also have the right to object to or restrict certain uses of your data or to complain to your local data protection authority.

Children

Interval is intended for people aged 13 and older. We don’t knowingly collect personal information from children under 13.

Changes to this policy

If we make a meaningful change to how we collect, use, or share your information, we’ll update the date above and let you know in Interval before the change takes effect.
