Privacy Policy

Privacy Policy

Last updated: October 6, 2026

Information we collect

None. Deckery has no user accounts and no backend servers. We have no way to read your entries, and we do not receive any personal information about you — not your name, your email address, your contacts, or your location history.

Where your data is stored

• Cards, text, tags, moods, and place names are stored in a local database on your iPhone.
• Photos you add are copied into Deckery's private storage on your device and compressed before saving.
• This data is inside the app's sandbox. No one but you — and the operating system on your own device — can access it. We cannot.

How your entries are processed

Turning your writing into a structured card happens entirely on your device. When your device supports it, Deckery uses Apple's on-device foundation model (Apple Intelligence). On other devices it uses Apple's on-device Natural Language framework together with built-in rules. Either way:

• Your text is never sent to us or to any third party.
• No AI service, cloud API, or remote model is involved.

Permissions we ask for, and why

• Photos — only when you tap Photos to attach an image. You pick exactly which images Deckery may use; the app does not have access to your whole photo library. Chosen images stay on your device.
• Location — only when you tap Place while writing a card, so the card can be labelled with where you are. iOS converts your coordinates to a place name using Apple's geocoding service; only that place name is stored on your device, and Deckery does not save your coordinates. Deckery does not use background location and does not track your movements.
• Microphone and Speech Recognition — only while you hold the button to dictate a card. Transcription runs entirely on your device and is never uploaded. If a device cannot transcribe speech on-device, Deckery does not start dictation at all rather than send your audio to a speech server — you can simply type instead.
• Health (HealthKit) — if you choose a mood, Deckery can save it to Apple Health as a State of Mind. This is write-only: Deckery never reads your health data, and it never leaves your device. You can decline this at any time in the Health app.
• Journaling Suggestions — only when you tap Moments, which opens Apple's own suggestion picker. You decide whether to insert a suggestion. Deckery does not read your Journal or your other apps' data in the background.

You can change or revoke any of these permissions at any time in iOS Settings.

Purchases

Deckery Pro is sold through Apple's App Store and processed entirely by Apple using StoreKit. We never receive your name, payment card details, or billing address. Apple provides only an anonymous, verified receipt confirming that a purchase exists, which is what allows Deckery to unlock Pro features. Apple's handling of your purchase is governed by Apple's own privacy policy.

Analytics, advertising, and tracking

None. Deckery contains no analytics SDKs, no advertising SDKs, no crash-reporting SDKs, and no third-party code of any kind. We do not use the Advertising Identifier (IDFA), we do not build profiles, and we do not track you across apps or websites. That is why Deckery never asks for tracking permission — it does not track.

Network activity

Deckery does not operate any server of its own. Your entries, photos, and moods are never sent to us or to any third party, and there is no sync, no telemetry, and no remote logging.

Two features do use the internet, and both talk only to Apple:

• Purchases — when you buy or restore Deckery Pro, Apple's App Store contacts Apple's servers to process and verify the purchase. Apple makes that connection and handles your payment details; we never see them.
• Place lookup — when you tap Place while writing a card, iOS asks Apple's geocoding service to turn your coordinates into a place name (for example, "Brooklyn, New York"). That lookup goes to Apple, not to us. Only the resulting place name is stored on your device — your coordinates are not saved by Deckery.

Nothing else in the app contacts the network. And because Deckery has no server of its own, there is nowhere for your writing to be sent even in principle.

Data retention and deletion

Your entries stay on your device for as long as you keep them, and we keep nothing at all. You are always in control:

• Delete a single card from the card's editing screen.
• Delete everything at once from Export → Data → Delete all data.
• Deleting the app removes its local data from your device as well.

Your privacy rights

Under regulations such as the GDPR and the CCPA/CPRA, you have rights to access, correct, export, and delete your personal information, and to opt out of its sale or sharing. Because Deckery collects nothing and we hold no personal information about you, there is nothing for us to look up, hand over, or erase on your behalf — and nothing has ever been sold or shared. Your data is already entirely in your own hands, on your own device. If you have questions about this, you are welcome to contact us using the details below.

Children's privacy

Deckery is not directed to children under 13, and we do not knowingly collect information from anyone — including children. Since the app collects no data at all, there is nothing for a parent to request the deletion of.

International users

Deckery does not transfer your data across borders, because your data is never collected or transmitted in the first place.

Terms of use

Your use of Deckery is governed by Apple's Standard End User License Agreement, together with any additional terms shown at the point of purchase.

Changes to this policy

If we ever change how Deckery handles data, we will update this page and revise the date at the top. Any material change will also be noted in the app's release notes. Because the app is built to keep your data on your device, we do not expect this policy to change often.
