Privacy Policy

Stampiary is an iOS app published by Shubham Wagh, an individual developer (not a company). We’re a small, single-developer operation — there is no larger corporate entity behind this app.

The photos you capture, the stamps you create, and the scrapbook pages you build are stored locally on your device only. Stampiary has no cloud storage or account system, and there is no feature in the app that uploads your photos or pages to us or to any third party. If you use the app’s “Save to Photos” or share features, that content goes wherever you choose to send it (your Photos library, Messages, Mail, etc.) — not through our servers.

Deleting the app, or deleting a stamp or page inside it, permanently removes that content from your device. We have no copy of it anywhere.

Stampiary asks for the following device permissions, each only when needed for a specific feature:

• Camera — to capture the photo that becomes a stamp. Required for the app’s core capture feature.
• Photo Library (add-only) — only when you tap “Save to Photos,” to write the finished stamp image into your library. We do not read your existing photo library.
• Notifications — optional, to send reminders and seasonal content you can opt into or turn off at any time in iOS Settings.
• App Tracking Transparency — optional, described in its own section below.

Declining any of these limits only the specific feature it powers, not the rest of the app.

We collect a limited set of information to understand how the app is used and to run our subscription and (where enabled) install-attribution and notification systems:

• Usage analytics — anonymous, aggregated app-usage events (for example, that a stamp was captured or saved, or that the app was opened), collected via Mixpanel. This does not include the content of your photos, stamps, or pages.
• Purchase and subscription information — if you purchase a Stampiary subscription or one-time pack, Apple processes the transaction through the App Store, and our paywall provider, Superwall, receives subscription status (active/expired, plan type) to unlock the corresponding features. We do not receive or store your payment details; Apple handles all billing directly.
• Install attribution — to understand which marketing channels lead to app installs, we use Kochava, which may receive device- and install-level signals such as your device’s advertising identifier (only if you grant App Tracking Transparency permission), Apple’s SKAdNetwork/AdAttributionKit data, and general device information (device model, OS version, general region). This is standard mobile-advertising attribution data, not the content you create in the app.
• Push notifications — if you enable notifications, we use Pushwoosh to deliver them, which requires a device push token. We do not send notification content that includes your private photos or page contents.
• Crash and diagnostic data — standard technical data (device type, OS version, and crash logs) may be collected automatically by Apple and our infrastructure providers to help us fix bugs.

• To operate core app features, including subscriptions and content unlocks.
• To understand overall usage patterns and improve the app.
• To measure which marketing efforts (for example, an ad campaign) led to an install, so we can spend our marketing budget responsibly.
• To send you notifications you’ve opted into, such as reminders or seasonal content updates.
• To diagnose and fix crashes or bugs.

We do not sell your information to third parties.

Stampiary offers a free tier (unlimited stamp captures, 2 scrapbook pages, and a starter set of stickers) alongside an optional auto-renewing subscription, Stampiary Plus, which unlocks the full sticker library, the background remover, unlimited pages, and PDF export. Subscription options are Weekly, Monthly, Yearly, or a one-time Lifetime purchase; individual sticker packs can also be purchased à la carte.

• Payment is charged to your Apple ID account at confirmation of purchase.
• Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period.
• Your account will be charged for renewal within 24 hours prior to the end of the current period, at the price of the selected plan.
• You can manage or cancel your subscription any time in your device’s Settings → [your name] → Subscriptions, or via the App Store. Cancelling stops future renewals; it does not refund the current period.

All billing is handled directly by Apple — we never see or store your card details.

• Apple — App Store purchases, SKAdNetwork/AdAttributionKit, push notification delivery infrastructure
• Superwall — paywall presentation and subscription status
• Mixpanel — product usage analytics
• Kochava — install attribution measurement
• Pushwoosh — push notification delivery

Each of these providers has its own privacy practices governing the data they process on our behalf. We only share the categories of information described above — never your photos, stamps, or page contents.

On iOS, we ask for App Tracking Transparency (ATT) permission before collecting any identifier that could be used to track you across other companies’ apps or websites (for example, your device’s advertising identifier for attribution purposes). You can allow or decline this at any time in your device’s Settings → Privacy & Security → Tracking. Declining does not limit any feature of the app itself.

Analytics and attribution data is retained by our providers (Mixpanel, Kochava, Pushwoosh) for as long as reasonably necessary for the purposes described above, in line with their own retention practices. Content you create in the app (photos, stamps, pages) is retained only on your own device, for as long as you keep the app installed and the content undeleted.

Depending on where you live, you may have rights to access, correct, or delete personal information we hold about you, or to object to certain processing. Because Stampiary stores your actual content locally on your device rather than on our servers, the most direct way to exercise these rights over your content is simply to delete it in the app, or delete the app itself. For anything else — analytics or attribution data held by our third-party providers — contact us at the email below and we will help coordinate a request.

Stampiary is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will address it.

We may update this policy as the app’s features change — for example, as attribution or notification providers are added. We’ll update the effective date above when we do. Continued use of the app after a change means you accept the updated policy.
