At Linkalia, we take the privacy of our users very seriously. This policy clearly explains what information we collect, why we collect it, and how we protect it.
1. Who is responsible
The data controller is the developer of Linkalia. You can contact us at any time at info@linkalia.org.
2. What data we collect
Anonymous device identifier
When you open the application for the first time, a unique random identifier (UUID) is automatically generated on your device. This identifier is not linked to your name, email address, phone number, or any personal data. It is used solely to manage your collections and your storage quota on the server.
Username (optional)
You may choose a visible name to identify yourself in collaborative collections. This name is entirely free — you can use a pseudonym or any text you prefer. We do not verify it or link it to any real identity. We store it on our server alongside your anonymous identifier, so that we can help you if you write to us and for our internal statistics. If you change it in Settings, the new one replaces the old one.
Content you provide
The links, documents, images, and files you save in Linkalia are stored on servers located in the European Union (Cloudflare R2, EU jurisdiction). This content belongs to you and you control it at all times.
Subscription data
If you purchase a Premium subscription, the transaction is handled entirely through Google Play. Linkalia only receives confirmation that the subscription is valid — we do not have access to your credit card, payment data, or billing information.
Link previews
To show the title and image of a link you save, the app reads that page directly from your device. Only if that does not work (some sites, such as Instagram or LinkedIn, block it), it sends the link's address to one of these external preview services: noembed.com and microlink.io. These services receive only the link's address and, as with any internet connection, your device's IP address. They do not receive your name, your identifier, your collections or your documents.
Backups
The app automatically backs up your Private collections to a folder of your choice on your device; Linkalia does not send that backup to any server. With a Pro subscription it can also keep a cloud backup (once a day, on Wi-Fi only) of your Private collections and their documents. That backup is stored on our servers in the European Union (Cloudflare R2, EU jurisdiction), linked to your anonymous identifier, counts towards your Pro storage and you can delete it at any time from the app. Linkalia does not use Android backup.
Recovering your account
So that you do not lose your account when you reinstall the app or switch phones, you can recover it in two ways:
- With your Google Play subscription (if you are Pro): the freshly installed app sends the purchase receipt to our server to find the account it belongs to. We receive no other data from Google Play.
- With "Continue with Google" (optional): if you choose to link your Google account, Google gives us an identifier for that account and your email address. We keep them only to recognise you when you want to recover your account and to show you which Google account is linked. We do not send you emails or use them for anything else. If you unlink it from the app, we delete them immediately.
Pro gift codes
If you redeem a gift code, we record which account redeemed it, with which linked Google account and when, so that each code is used only once and each person can redeem only one.
Date of last connection
Each time you open the app, we store the day you did so (the date only, no time) alongside your anonymous identifier. Each day replaces the previous one, so there is no history of when you use the app or what you do in it. We use it to know how many accounts are still active and to identify inactive accounts.
Anonymous usage statistics
To learn which features are used and which to improve, the app collects usage statistics that never include what you save: no links, titles, notes, collection names or files. You can turn them off at any time in Settings → Anonymous statistics. There are two kinds:
- Totals on our server: once a day, the app sends a few counts alongside your anonymous identifier: how many collections and items of each type you have (links, photos, videos, documents), how often you have saved from the Share menu or from the app itself, how many days you have opened it, and the app's version and language. Each upload replaces the previous one, with no history.
- Google Analytics for Firebase: the app records individual actions, such as opening it, saving an item, creating or sharing a collection or finishing the introduction, together with technical device data (model, Android version, app version) and the approximate country or city that Google infers from the IP address. It uses a random identifier specific to this installation, different from your Linkalia identifier. We have set it up with no advertising identifier, no data for ads or personalisation, and a data retention of 2 months. Google acts as a data processor and may process the data outside the European Union, under the safeguards of the EU-US Data Privacy Framework. You can review its policy at policies.google.com/privacy.
3. What data we do NOT collect
- Real name or phone number, nor your email address unless you link your Google account
- Precise location (GPS); at most, the approximate country or city that Google Analytics infers from the IP address
- Browsing data, or which links or documents you save or open
- Device contacts
- Advertising identifiers
- Any form of cross-app tracking
4. How we use your data
- To store and synchronise your collections between devices and collaborators
- To manage your account's storage quota
- To verify the status of your Premium subscription
- To keep the cloud backup of your Private collections (Pro) and restore it when you need it
- To help you recover your account when you reinstall the app or switch phones
- To know how many accounts are still active (internal statistics based on the date of last connection)
- To learn which features are used and improve the app (anonymous usage statistics, which you can turn off)
We do not use your data for advertising, nor do we share it with third parties for commercial purposes.
5. Where data is stored
All content you upload to collaborative collections or Spaces is stored on Cloudflare servers under European Union jurisdiction. Cloudflare holds the relevant security certifications (ISO 27001, SOC 2). You can review their privacy policy at cloudflare.com/privacypolicy.
Private collections are stored on your device and are not sent to any server, unless you are Pro and use the cloud backup; in that case the backup is kept on those same European Union servers.
6. How long we retain data
Your content remains on our servers for as long as you have the application installed and active. If you delete a collaborative collection, the content is permanently and immediately removed. If you delete the cloud backup or unlink your Google account from the app, that data is also deleted immediately. To delete all your data, write to info@linkalia.org with your account identifier (available in Settings) and we will delete it within 30 days.
7. Your rights
Under the GDPR you have the right to:
- Access: know what data we hold about you
- Rectification: correct inaccurate data
- Erasure: request deletion of your data
- Portability: receive your data in a readable format
- Objection: object to certain types of processing
Write to us at info@linkalia.org. We will respond within 30 days.
8. Security
All communication between the application and our servers uses HTTPS with TLS encryption. Access tokens are stored as SHA-256 hashes and never in plain text. Your anonymous account identifier is generated locally and does not allow you to be identified. A Google account is only linked after a Google sign-in verified on our server.
9. Minors
Linkalia is not directed at children under the age of 16. If you are under 16, please do not use the application without the consent of your legal guardian.
10. Changes to this policy
If we make significant changes, we will notify you within the app. The date of the last update always appears at the top of this document.
11. Contact
You may also file a complaint with the Spanish Data Protection Agency (AEPD).
