Effective date: June 14, 2026 · A product of Nieves Studio LLC
Horizon (“we,” “us,” or “the app”) is a personal planner with optional calendar
sync, operated by Nieves Studio LLC. This policy explains what information the app
collects, how it is used, and the choices you have. By using Horizon you agree to
the practices described here.
Information we collect
Account information. When you create an account we collect your
email address (and display name, if you provide one). You may sign in with email and
password or with Google Sign-In. Authentication is handled by our backend provider,
Supabase.
Planner content. The notes, goals, tasks, projects, and entries you
create (daily, weekly, quarterly, and annual) are stored so they can sync across your
devices and be restored if you reinstall the app.
Google Calendar data (optional). If you choose to connect Google
Calendar, the app accesses your calendar to read and create events on your behalf. This
access is used solely to display and manage your events inside Horizon and only while you
keep the connection enabled. You can disconnect at any time.
Diagnostic data. To keep the app stable we use Sentry to collect crash
reports and basic error/diagnostic information. This does not include the content of your
planner entries.
Device notifications. If you enable reminders, they are scheduled locally
on your device.
How we use your information
To provide, sync, and back up your planner across your devices.
To authenticate you and keep your account secure.
To display and manage your Google Calendar events, if you connect them.
To diagnose crashes and improve the app’s reliability.
To send the reminders you enable.
How your information is stored
Your account and planner data are stored in our cloud database (Supabase) and cached locally
on your device for offline access. Data is transmitted over encrypted connections (HTTPS).
Access to your data is restricted to your own account.
Google API Services
Horizon’s use of information received from Google APIs adheres to the
Google API Services User Data Policy,
including the Limited Use requirements. We do not use Google Calendar data for advertising,
and we do not sell it or share it with third parties except as needed to provide the app’s
features to you.
Sharing
We do not sell your personal information. We share data only with the service providers that
operate the app on our behalf — Supabase (database and authentication), Google (sign-in and,
if enabled, Calendar), and Sentry (crash reporting) — and only to the extent needed to provide
these features. We may disclose information if required by law.
Your choices and rights
Access and update. You can view and edit your profile and planner data in
the app at any time.
Disconnect Calendar. You can disconnect Google Calendar from within the app.
Delete your account. The app’s “Delete account” option erases your planner
data. You may also contact us to request deletion.
Data retention
We retain your data for as long as your account is active. When you delete your account or your
data, it is removed from our systems, subject to any retention required by law.
Children
Horizon is not directed to children under 13, and we do not knowingly collect personal
information from them.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by updating the
effective date above.
