Effective date: August 10, 2026
This Privacy Policy explains how Llama App Studios ("we," "us," or "our") collects, uses, and shares information when you use the OurStickerBook mobile application (the "App"). We are based in Toronto, Ontario, Canada.
If you have questions or requests about your data, contact us at llamaappstudios@gmail.com.
Account information. You can use the App anonymously or sign in with Apple, Google, or an email address. Depending on the method, we receive your name, email address, and profile photo. Anonymous accounts have no personal identifiers beyond a randomly generated user ID.
Content you create. Photos you capture or import, the stickers made from them, book titles, page text, secret messages, and profile pictures. This content is uploaded to our servers so it can sync across your devices and with members of your shared books.
Book membership. When you create or redeem an invite, we record which books you belong to and which books you own.
Device and usage data. We use Google Firebase to operate the App, which collects device identifiers, coarse device information (model, OS version, language), crash and diagnostic data, and app interaction events (such as which screens are used). We use this to run, debug, and improve the App.
Push notification tokens. If you enable notifications, we store a device token so we can notify you, for example when someone adds a stamp to a shared book.
Presence. While you have a shared book open, we briefly record that you are active so book-mates can see you are there. This is a timestamp, not your location.
Advertising data. If you choose to watch rewarded ads (free tier only), Google AdMob collects device advertising identifiers and related data to serve and measure ads. Where required, we ask for your permission through Apple's App Tracking Transparency prompt, and you can decline without losing access to the App.
Purchase state. Purchases are processed by Apple. We receive entitlement information (for example, that your device has an active subscription) but never your payment details.
We do not collect your precise location, contacts, or health data. We do not scan or analyze the content of your photos for advertising. Sticker cut-out and rendering happen entirely on your device.
We use the information described above to:
provide the core service: storing your books and stickers, syncing them across devices, and sharing them with the members of your books;
send push notifications you have enabled;
enforce daily quotas and deliver purchased features;
serve optional rewarded ads to free-tier users;
measure aggregate usage, diagnose crashes, and improve the App;
remotely configure features and limits; and
comply with legal obligations and enforce our Terms of Service.
We do not sell your personal information, and we do not use the photos you upload for marketing, advertising, or training machine-learning models.
OurStickerBook is a social app by design:
Content you place in a shared book is visible to all members of that book, and members can edit or remove content within the book.
Your display name and profile photo are visible to users you share a book with.
Your personal shelf and books that you have not shared are visible only to you.
Only invited members can access a book. There are no public books, public profiles, or discovery features.
We use a small number of service providers to operate the App:
Google Firebase (Google LLC) — authentication, database, file storage, push notifications, analytics, remote configuration, and cloud functions. Your content and account data are stored on Firebase servers, currently located in the United States.
Google AdMob (Google LLC) — rewarded video advertising for free-tier users. AdMob's use of data is described in Google's privacy policy and how Google uses information from ads.
Apple — sign in with Apple, App Store purchases, and push notification delivery, under Apple's own privacy policy.
These providers process data on our behalf (or, in the case of ads and purchases, as independent controllers) and are not permitted to use your content for their own purposes beyond what is described in their policies.
We are a Canadian business, and our service providers store data primarily in the United States. By using the App, you understand that your information is transferred to and processed in countries other than your own, which may have different data protection laws. We rely on our providers' standard contractual safeguards for these transfers.
While your account is active, we keep your content so your books remain available to you and your book-mates.
Deleting content. Stamps, pages, and books you delete are removed from the App for all members.
Deleting your account. You can delete your account at any time in the App's settings. This permanently deletes your profile, your owned books and their images, your personal shelf, your notification tokens, and your authentication record from our systems. Content you contributed to books owned by other users remains part of those books unless you delete it first.
Residual copies may persist in encrypted backups for a limited period before being purged. Aggregated analytics that cannot identify you may be retained.
Data is encrypted in transit, and access to book content is enforced server-side so that only a book's members can read or write it. No system is perfectly secure, so please use the App's sharing features thoughtfully and keep your sign-in credentials safe.
The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has created an account, contact us at llamaappstudios@gmail.com and we will delete it.
Depending on where you live (including under Canada's PIPEDA, the EU/UK GDPR, and US state privacy laws), you may have the right to access, correct, export, or delete your personal information, to object to or restrict certain processing, and to withdraw consent.
You can exercise most of these rights directly in the App: edit your profile in settings, delete individual content, or delete your account entirely. For anything else — or to lodge a concern — email us at llamaappstudios@gmail.com. You may also complain to your local data protection authority; in Canada, that is the Office of the Privacy Commissioner of Canada.
App Tracking Transparency. You can allow or deny tracking for ads in the iOS prompt or later in iOS Settings → Privacy & Security → Tracking.
Rewarded ads are always optional. They only appear when you choose to watch one, and premium subscribers never see ads.
Push notifications can be turned off in iOS Settings at any time.
We may update this Privacy Policy from time to time. If we make material changes, we will notify you in the App or by other reasonable means before the changes take effect. The effective date at the top indicates the latest revision.
