Privacy Policy
Last updated: September 23, 2026
Overview
Estoka is an app that helps you save, organize, and find content you discover across the web — links from Instagram, TikTok, Threads, Spotify, YouTube, and beyond — in one library. This policy explains what information we collect when you use Estoka, why we collect it, who we share it with, and the choices you have.
It applies to the Estoka Android app and this website.
Information we collect
We only collect what Estoka needs to work. Here is the full list.
Account information
When you sign in with Google, our authentication provider (Firebase Authentication) provides us with your:
- Email address
- Display name
- Profile photo URL
- A unique user ID (UID) that identifies your account
We do not receive or store your Google password, and we do not receive or store passwords for any other platform.
Content you save
The items you save, and the folders and tags you organize them into, are stored in our database (Cloud Firestore) under your UID:
- Saved items: the source URL, title, thumbnail image URL, creator or handle, source platform, any tags you apply, the folders it belongs to, and the saved timestamp.
- Folders: name, color, and icon.
- Tags: label.
- Settings: your reminder preferences.
Device and reminder information
If you turn on reminders, we store a device push notification token (through Firebase Cloud Messaging) so we can deliver those notifications to your device.
What we do not collect
- Passwords for other platforms.
- Private or non-public content from source platforms.
- Precise location.
- Payment information — Estoka has no purchases at this time.
How we use your information
We use the information above to operate Estoka and nothing else. In practice, that means:
- Saving the content you send to Estoka and displaying its preview.
- Organizing your library by folders, tags, and saved date.
- Letting you search, retrieve, and export your library.
- Sending you reminders, but only if you have enabled them.
- Keeping your account and data in sync across your devices.
We do not use your data for advertising or ad targeting, and we do not sell your data to anyone.
Third-party services
We rely on a small number of service providers to run Estoka:
- Firebase / Google Cloud hosts our authentication and our database.
- Cloudflare runs the backend compute that fetches link previews and generates data exports.
- The source platforms — when you save a link, our backend requests the same public preview information anyone would see from that link (title, thumbnail, creator). We do not sign in to, or access private data on, Instagram, TikTok, Threads, Spotify, or YouTube, and we do not send them any of your Estoka account data.
Data retention
We keep your information for as long as your account is active and as long as it is needed to provide Estoka to you. You stay in control of when that ends:
- Deleting an item, folder, or tag removes it from your library.
- Deleting your account permanently removes your account and all of the saved items, folders, tags, and settings tied to it. See the Account Deletion page to make a request.
Your rights and choices
You can manage your information directly:
- Access it: export your library from within the app as a JSON file.
- Delete it: remove any saved item, folder, or tag at any time.
- Delete your account: request permanent deletion of your entire account and its data via our Account Deletion page.
If you have questions about your information, contact us at [email protected].
Children's privacy
Estoka is not directed at children under 13, and we do not knowingly collect information from children under 13. If you believe a child has provided us with information, contact us and we will delete it.
Changes to this policy
If we make changes to this policy, we will post the updated version on this page with a new “Last updated” date. We encourage you to review this page periodically.
