O Odak

Privacy Policy

Odak · Beydemir Technology · Last updated: August 18, 2026

This Privacy Policy explains how Beydemir Technology ("we", "us", "the developer") handles information in connection with the "Odak" mobile application (the "App", package name com.beydemir.odak). By downloading and using the App, you agree to the data practices described in this policy.

Odak is, first and foremost, a personal planner that runs on your device. Most of your data never leaves your phone. The sections below clearly identify the specific cases where data does leave the device.

1. What this policy covers

Odak is a productivity app offering task/to-do management, a calendar, notes, location-based reminders, an AI-powered chat feature called "AI Coach", optional cloud backup, and an optional subscription ("Odak Plus"). This document explains what data the App collects, how it is used, who it may be shared with, and what rights you have.

2. Data we collect and how we use it

2.1. Data stored locally on your device

The following data is stored only on your own device (in a local database and local preference storage) and is never sent to any server operated by us:

This data is used to provide the App's core functionality (task/note management, reminder notifications, statistics, home-screen widgets). No account system is required to use the App's core features, so this data is not transmitted to us and only you can access it.

Note: Depending on your device's operating system settings, Android's "automatic backup" feature may include the App's data in a cloud backup associated with your own Google account. This process is managed by Google; we do not have access to these backups.

2.2. Data sent to third parties for the AI Coach feature

When you chat with AI Coach or use smart/voice task entry, the following information is sent over the internet to third-party AI providers — Google's Gemini API and/or Groq API (used as an alternative/fallback provider) — in order to generate a relevant response:

This data is sent only to generate a response to that specific request; we do not store it on any server of our own. However, this data does reach Google's (Gemini API) or Groq's servers for processing, and is handled under each provider's own privacy policy:

If there is no internet connection, AI Coach falls back to a simple on-device offline response mechanism, and in that case no data is sent to any external service.

2.3. Location data (only if you turn it on)

The location-based reminders feature accesses your location only after you enable it yourself. To notify you when you approach or leave a place you've saved (Home, Work, etc.), the App uses the device's geofencing service and the background location permission.

2.4. Cloud backup (optional, only if you turn it on)

When you enable cloud backup, an encrypted (AES-256) copy of your data is uploaded to a private, app-specific space (appDataFolder) in your own Google Drive account, using Google Sign-In to authenticate. Only Odak can access this space — no other user, and not us, can see it. Secure Notes are never included in this backup.

Odak requests a single Google scope for this feature, https://www.googleapis.com/auth/drive.appdata, which grants access only to the App's own hidden folder and gives no access to any other file in your Drive.

Our use of Google Drive data obtained through this feature complies with the Google API Services User Data Policy, including the Limited Use requirements: this data is used only to upload/restore your own backup at your request, is never used for advertising, is never read by humans, and is never transferred to third parties.

2.5. Subscriptions and purchases (Odak Plus)

Odak offers an optional subscription ("Odak Plus") and one-time purchase processed through Google Play Billing. Payment is handled entirely by Google; we never receive or store your card or financial details. Google may share limited purchase/subscription status information with us (e.g. whether you have an active subscription) so the App can unlock the corresponding features.

2.6. Contacts (address book)

In the "task actions" feature (calling/messaging/emailing directly from a task with one tap), you pick a contact via the system contact picker. Only the selected contact's number/email and label are stored locally on your device, in order to perform that action. We do not read, copy, or send your entire address book to any server.

2.7. Advertising (Google AdMob)

To support the App being offered free of charge, the App displays banner, interstitial, rewarded, and app-open ads through Google AdMob (Google Mobile Ads SDK). No ads are shown under an active Odak Plus subscription. Google may collect the following types of data for ad delivery, measurement, and (to the extent you have consented) personalisation:

This data collection is carried out directly by Google, under Google's own privacy policy and advertising policies:

You can manage your ad personalisation preferences from your device settings (Google Settings > Ads).

2.8. Notifications

Task reminders and daily/weekly summaries are scheduled entirely on your device using Android's local notification and alarm systems, and (for location-based reminders) the device's geofencing service. No data is sent to any server for these notifications; the App does not use a remote/push notification infrastructure.

3. Third-party services

Odak uses the following third-party services. Each is governed by its own privacy policy:

4. Data we do not collect

For clarity, Odak does not:

5. Data sharing and sale

We do not sell your personal data. We share data only with the service providers listed in section 3, only to the extent necessary to provide the relevant feature, and only for that purpose. We may disclose data where required by applicable law.

6. Permissions used

The App requests the following Android permissions in order to provide its features:

None of these permissions are used to collect data in the background beyond the specific feature they enable.

7. Data security

Data stored locally on your device is protected by the standard app-level protections provided by the Android operating system (app-specific private storage). Secure Notes and cloud backups are additionally encrypted (device-bound key / AES-256, respectively). Communication with the AI Coach, advertising, billing, and cloud-backup services is carried out over encrypted connections (HTTPS/TLS). However, no method of transmission over the internet or electronic storage can be guaranteed to be 100% secure.

8. Data retention and deletion

Your tasks, notes, saved places, and chat history remain stored on your device until you delete them or uninstall the App. You can delete this data by:

If you have enabled cloud backup, you can delete it by turning the feature off in the App, or by revoking Odak's access from drive.google.com > Settings > Manage apps > Odak > Delete hidden app data / Disconnect. You can revoke Odak's access to your Google Account at any time from myaccount.google.com/permissions.

Since requests sent to AI Coach are not stored by us, please refer to the relevant provider's own policy (Google, Groq) regarding how long they process or retain such data on their side.

9. Children's privacy

Odak is not directed at children under the age of 13, and we do not knowingly collect data from users in this age group. If you believe a child under 13 has provided us with data, please contact us using the information in section 11; we will take appropriate action promptly.

10. Your rights

Because most of your data is stored locally on your device, you directly control access to, correction of, and deletion of your data (through the App's interface and your device settings). Depending on your jurisdiction (e.g. under regulations such as GDPR or Turkey's KVKK), you may have additional rights to access, correct, delete, or restrict processing of your data. You can contact us using the information in section 11 to exercise these rights or ask questions.

12. Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes, we will post the updated policy on this page and update the "Last updated" date at the top. Your continued use of the App after any changes constitutes your acceptance of the updated policy.
