ChillDone

Last updated: September 23, 2026

ChillDone is an app for two paired people to share and keep track of tasks between them. This page explains what data the app handles, why, where it is stored, how long it is kept, and how you can delete it.

Who is responsible

ChillDone is developed and operated by Sergio Estrada Valenzuela, published on Google Play under the developer name "smartdevapps". Contact: nesteddevs@gmail.com.

We don't ask for a traditional account

The app doesn't ask for your name, email, or password. The first time you open it, each phone receives an anonymous identifier generated by Firebase Authentication (anonymous authentication), with no personal data attached to it.

What data we collect and why

Anonymous identifier (Firebase Authentication): to tell your phone apart from your partner's.
Pairing code: the 6-character code generated when you invite your partner; it expires after 24 hours.
Task content: title, description, and status of your tasks. They are stored on your phone; to reach your partner's phone they pass temporarily through Firebase (see "How long data is kept").
Evidence photos: if you attach a photo to a task, it is uploaded temporarily so your partner can download it, and then removed from the server. Each phone keeps its own local copy.
Push notification token (Firebase Cloud Messaging): to notify you about updates even when the app is closed.
Technical device identifier (ANDROID_ID): used only to keep the free trial from restarting when the app is uninstalled and reinstalled. It is not used for advertising or for tracking across apps. It only stays on the invitation (until it is accepted or expires) and on the pair record until the server records the trial start date (a few seconds), and is then removed from there; the only record kept is described below.
Firebase installation identifier: generated by the Firebase services so that notifications and the other services work. It is not linked to your name or identity.
Technical connection data: like any Internet service, Google's servers (Firebase, Google Play and the hosting of these web pages) receive your IP address and basic technical data when the app or your browser connects.
Access codes: if you redeem an access code (for example, a gift), we store which pair redeemed it, your anonymous identifier and the device ANDROID_ID, only to limit how many times a code can be used. If you delete your data, your identifier and ANDROID_ID are unlinked from that record.
Purchase data: if you buy the unlock, we store the Google Play purchase token and who paid in an internal record that neither you nor your partner can access, and the "unlocked" status on the pair record, to verify the purchase. Payment is processed by Google Play: we never see your card details.

What we DON'T collect

We don't ask for or store your name, email, phone number, location, contacts, or payment data. The app shows no ads and doesn't use third-party analytics or crash-reporting tools.

Who it's shared with

Your tasks and photos are only visible to the person you're paired with (and vice versa). To function, we use Google Firebase (Authentication, Firestore, Cloud Storage, Cloud Messaging, Cloud Functions) and Google Play Billing on the app's behalf: Google acts as a data processor. We don't sell or share your data with any other third party.

Where it is stored

Data that passes through the server is hosted in the United States (Google Cloud: Firestore in the nam5 multi-region, Cloud Storage in us-east1 and Cloud Functions in us-central1).

How long data is kept

On your phone: tasks and photos are kept until you delete them, delete your data, or uninstall the app. If Android backup is turned on, the system may include this local data in your Google account backup; Google manages it and you can delete it from your Google account's backup settings.
Messages between phones: removed from the server as soon as your partner receives them. If they are never received, they are deleted automatically shortly after they expire at 3 days (usually within a day).
Temporary photos: removed when your partner downloads them; if never downloaded, automatically deleted after 20 days at most.
Invitations: expire after 24 hours and are deleted automatically shortly after.
Pair record: holds only the anonymous identifiers, the trial start date and the unlock status (it does not keep your ANDROID_ID), until both people delete their data.
Access code redemption: the redemption record is kept without your anonymous identifier or ANDROID_ID once you delete your data; the use already consumed by the code is not given back.
Per-device trial record: the trial start date tied to the technical device identifier is kept, with no link to your anonymous identifier, to prevent abuse of the free trial.
If you only uninstall the app without using "Delete my data", the anonymous data on the pair record remains on the server. To remove it, use "Delete my data" before uninstalling, or write to us.

Deleting your data

You can delete your data at any time from the app (⋮ menu → "Delete my data"). See the details in Delete my data.

Your rights

You can ask us for access to, correction of, or deletion of your data. You can delete your data yourself from the app at any time. For any other request, write to nesteddevs@gmail.com; we reply within a reasonable time (30 days at most). Since we don't know your identity, we may need additional information to locate the anonymous identifiers that belong to you.

Children

ChillDone is not directed to people under 18 and we do not knowingly collect data from minors. If you believe a minor is using the app, write to us so we can delete their data.

Changes to this policy

If we update this policy, we'll change the "Last updated" date at the top of this page.
