Privacy policy

Last updated: September 2026

Constante is a personal app to organize tasks and reminders, goals and habits, and expenses and income. This page explains what information is stored, where it lives, and who can see it.

What's stored only on your phone

By default (guest mode, without signing in), all the information you enter —your name, tasks and reminders, goals, habits and their daily check-ins, categories, expenses, income, budgets, and your preferences (language, theme, sounds, tab order)— is stored only in a local database (SQLite) on your phone. None of this leaves your device or goes through any server.

Optional cloud backup

If you choose to sign in, you can turn on a backup of your data to a server (Supabase). It's entirely optional: the app works the same without signing in, and you can sign out at any time without losing what's on your phone.

When you're signed in and backing up:

• A copy of your data (tasks, goals, habits and their check-ins, expenses, income, budgets, categories and your preferences) is uploaded to a protected table on the server.
• The backup uploads automatically when you sign in, whenever the app goes to the background (at most every 5 minutes), and with the "Back up now" button in Settings.
• Each person can only read or write their own backup (row-level security, configured server-side); nobody else, not even with access to the project, can see another person's backup through the app.
• Alarm-style reminders (routines) don't travel in the backup yet — they stay only on the phone where they were created.

You can delete your backup at any time by deleting your account (see Delete account).

Signing in

There are two ways to sign in, and neither uses a password:

• With Google: you pick a Google account in the phone's own account picker. Constante only receives your name, your email, your profile picture and an identifier for your account, which it uses to identify you. It doesn't access your Gmail, contacts, files or any other data in your Google account.
• With an email code: you type your email and we send you a 6-digit code. The code isn't stored anywhere beyond the screen while you type it.

If you sign in with Google and with a code using the same email, it's the same account and the same backup.

Notifications and bank messages (automatic detection)

Constante can help you log expenses and income automatically by recognizing the notifications Nequi and Bancolombia SMS send to your phone. This feature:

• Is off by default and requires turning on "Automatic detection" in Settings and granting Constante notification access from Android's settings.
• Only reads, on your own phone, notifications whose text starts with "NEQUI:" or "Bancolombia:". Your other notifications aren't processed.
• Interprets that text with simple rules (no artificial intelligence or third-party services) to recognize the amount and whether it's an expense or income — all processing happens on your phone.
• That text is never sent to any server. Only if you confirm the transaction is the matching expense or income created in your local database (and it travels in the backup like any other expense or income, if you're signed in). Nothing is saved without your explicit confirmation.
• So you can diagnose why something wasn't detected, Constante keeps —only on your phone, visible in Settings— a log with the date and time of every bank notification received and its full text. For notifications that aren't from a bank, that log only stores the sending app's name and the time, never the text.

Error reporting

Today Constante doesn't send any error reports or usage statistics to any server. If anonymous error reporting is added in the future, this page will be updated to explain it before it's turned on.

What Constante doesn't do

• No ads.
• No third-party trackers or behavioral analytics.
• Never sells, rents, or shares your data with anyone.

Your rights

If you're a resident of Colombia, you have the rights granted by Law 1581 of 2012 on personal data protection (Habeas Data): to know, update and correct your data, request proof of the authorization given, be informed about how it's been used, revoke that authorization, and request deletion of your data when the law isn't respected. You can exercise these rights by deleting your account from the app (see Delete account) or by writing to the contact email below.
