By downloading or using Colla (“the app”) you agree to these Terms of Use. If you do not agree, do not use the app. Your use of the app is also subject to the Privacy Policy and to the terms of the store (Apple App Store or Google Play) you installed it from.
Colla is a photo collage editor. You select photos already on your device, arrange them into a collage, and save the result to your device photo library or share it through your device’s share sheet. Colla has no account and no Colla-operated server; editing happens on your device.
“Your content” means the photos you select and the collages you create with the app.
You are solely responsible for the photos you bring into the app. You confirm that, for each photo you use, you own it or have the necessary rights and permissions, including the rights of any people who appear in it. Do not use the app to create or share material that:
You agree not to reverse engineer (except to the extent this restriction is prohibited by applicable law), resell, sublicense, or commercially exploit the app itself; not to interfere with its normal operation; and not to use it in violation of any applicable law.
The app, including its name, its design, its layouts, templates, backgrounds, icons, and code, is owned by the provider or its licensors and is protected by intellectual-property law. These Terms grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the app on devices you own or control, for personal use, in the form distributed by the app store. No other rights are granted.
Colla is free to download and use for its core collage features. Some features are marked “Pro” and require a purchase to unlock (collectively “Colla Pro”). Which features are Free and which are Pro may change over time.
Colla Pro is offered as a single one-time purchase (“lifetime”). Colla does not sell subscriptions, and nothing renews.
All purchases are made through, and billed by, Apple (App Store) or Google (Google Play), not by the provider.
The price is shown in the app before you buy, in your local currency, as supplied by the store. The provider does not set or display prices anywhere else.
Colla Pro is a single one-time payment. It is not a subscription and does not auto-renew, so there is nothing to cancel. It unlocks the Pro features that the purchase covers for the supported lifetime of the app on your store account.
Refunds are handled solely by Apple or Google under the App Store / Google Play refund rules and their discretion. The provider cannot issue store refunds. Request a refund through:
If you reinstall the app or move to a new device using the same store account, use “Restore purchase” in the app to re-activate Pro. Restoring relies on your Apple or Google account records.
The provider may update, change, or discontinue the app or any feature (including moving features between Free and Pro) at any time. The provider may update these Terms; the updated version will be posted at its published location with a new effective date, and continued use after that constitutes acceptance.
The app is provided “as is” and “as available”, without warranties of any kind, whether express or implied, to the fullest extent permitted by applicable law. The provider does not warrant that the app will be uninterrupted, error-free, or that it will meet your requirements, and does not warrant any particular output quality. You are responsible for keeping your own copies of important photos; the app is an editor, not a backup service.
To the fullest extent permitted by applicable law, the provider will not be liable for any indirect, incidental, special, consequential, or exemplary damages, or for any loss of data, arising out of or relating to your use of or inability to use the app. Nothing in these Terms limits liability that cannot be limited under applicable law, including your statutory consumer rights, which are not affected by these Terms.
This licence ends automatically if you breach these Terms, and you may end it at any time by deleting the app. Sections that by their nature should survive termination (for example sections 3, 4, 6, 8.3, 10, 11, and 13) survive.
These Terms are governed by the laws of the Republic of Türkiye. Any dispute arising from these Terms will be handled by the courts and authorities that have jurisdiction under applicable Turkish law.
