## Glossary

- [AOSP](https://nerdy.pro/glossary#aosp): The Android Open Source Project — Android without the Google layer on top, which anyone may fork. Point-of-sale terminals, kiosks and in-car systems run on forks of it, and working at that level exposes parts of the OS an app developer never sees.
- [App Clips](https://nerdy.pro/glossary#app-clips): An Apple feature that runs a small slice of an iOS app — under 15 MB — without installing the whole thing. Invoked from a QR code, an NFC tag or a link, for when the first thing a user does should not require a store visit.
- [BigQuery](https://nerdy.pro/glossary#bigquery): Google Cloud's analytics warehouse. You point SQL at billions of rows and it scans them in seconds, on storage held separately from the machines doing the querying — which is what keeps reporting and exploration off the database that is serving live traffic.
- [CI/CD](https://nerdy.pro/glossary#ci-cd): Automation that builds, tests and ships every change without anyone running commands by hand. On mobile it is what turns a release into a button press instead of an afternoon of someone else being unavailable.
- [Container registry](https://nerdy.pro/glossary#container-registry): A hosted store for container images, addressed by name and tag — Docker Hub, GitHub Container Registry, or a cloud provider's own. Pushing a build there turns 'works on my machine' into an image anyone can pull and run unchanged.
- [CRUD](https://nerdy.pro/glossary#crud): Create, read, update, delete — the four operations behind almost every form and admin screen. Shorthand for the routine data-management half of an app, as opposed to the parts carrying real domain logic.
- [Deep linking](https://nerdy.pro/glossary/deep-linking): A link that opens a specific screen inside an installed app instead of its home screen or a web page. Deferred deep linking survives an install, so a tap that leads through the app store still lands on the right screen.
- [Dev Container](https://nerdy.pro/glossary#dev-container): A development environment described once in devcontainer.json — the OS, tools, and runtime versions a project needs — and opened identically inside a container by every contributor's editor, instead of a setup guide everyone interprets differently.
- [Elasticsearch](https://nerdy.pro/glossary#elasticsearch): A search and analytics engine that indexes records so they can be filtered and searched interactively instead of scanned. What you reach for when the question is "show me these particular sessions, narrowed six ways" rather than "sum this column".
- [End-to-end encryption](https://nerdy.pro/glossary#end-to-end-encryption): Encryption applied on the sending device and undone only on the receiving one, so the service carrying the message cannot read it — not under subpoena, not after a breach. It protects the content and never the metadata.
- [Fan-out](https://nerdy.pro/glossary#fan-out): Reading an upstream source once and delivering each update to every client subscribed to it. The naive version writes to subscribers in a loop and stalls the moment one socket is slow; a real one buffers per client and drops whoever cannot keep up.
- [Feature flags](https://nerdy.pro/glossary#feature-flags): Switches that turn functionality on or off from configuration rather than from a release. They let one binary behave differently per brand, market or user, and let a risky feature be shut off without shipping a new build through review.
- [Floating point](https://nerdy.pro/glossary#floating-point): The IEEE 754 binary format behind double and float. It cannot hold 0.1 exactly, so 0.1 + 0.2 is 0.30000000000000004 — invisible in graphics and fatal in money, which belongs in integer minor units or a decimal type instead.
- [GDPR](https://nerdy.pro/glossary#gdpr): The EU regulation covering personal data of people in the EU: a lawful basis for collecting it, real consent for tracking, and rights to see and delete it. It follows your users, not your servers, so it applies wherever the company is registered.
- [Golden test](https://nerdy.pro/glossary#golden-test): A test that renders a widget and compares the result pixel for pixel against a stored reference image. In Flutter it is the cheapest way to answer whether a redesign broke the empty state at 320pt, in dark mode, at 200% text scale.
- [GraphQL](https://nerdy.pro/glossary#graphql): A query language for APIs where the client names exactly the fields it wants and gets one response shaped to match. It removes the over-fetching REST endpoints drift into, and adds a failure mode of its own: an unbounded query that walks the whole data model.
- [Headless CMS](https://nerdy.pro/glossary#headless-cms): A content system with an editor and an API but no front end of its own. Editors publish in one place, and the site or app renders that content itself — so the presentation layer is yours rather than the CMS vendor's.
- [HIPAA](https://nerdy.pro/glossary#hipaa): The US law governing protected health information — how it may be stored, transmitted, logged and disclosed. Like PCI-DSS it is an architectural constraint chosen at the start, not a policy document added before launch.
- [Host Card Emulation](https://nerdy.pro/glossary#host-card-emulation): Letting an Android phone act as a contactless card over NFC in software, with no hardware secure element. It is how a wallet app pays at a terminal: the phone speaks the same EMV contactless protocol the plastic card would have.
- [Impeller](https://nerdy.pro/glossary#impeller): The rendering engine Flutter uses today, default on iOS since 2023 and on Android since 2024. It compiles its shaders ahead of time instead of during the first animation, which removed the shader-compilation jank that was Flutter's most visible production problem.
- [In-app purchase](https://nerdy.pro/glossary#in-app-purchase): Selling digital goods or a subscription through the Apple or Google billing that both stores require for digital content and take a commission on. The hard part is never the purchase; it is restoring it on a new device and keeping entitlement state honest.
- [Install Referrer](https://nerdy.pro/glossary#install-referrer): A Google Play API that hands a freshly installed Android app the campaign parameters from the link that led to the install. The Android half of deferred deep linking, and the dependable way to attribute where a user came from.
- [JWT](https://nerdy.pro/glossary#jwt): A signed token carrying its own claims, so a server can tell who a request belongs to without looking a session up. Standard for mobile authentication. The signature proves it was not altered; it does not hide what is inside.
- [Kotlin Multiplatform](https://nerdy.pro/technologies/kmp): Sharing business logic written in Kotlin across Android, iOS and the server while each platform keeps its own native UI. The alternative to Flutter when the interface has to be native but the rules behind it do not.
- [KYC](https://nerdy.pro/glossary#kyc): Know Your Customer — the identity checks a regulated financial product runs before it lets anyone move money: document capture, liveness, sanctions and anti-money-laundering screening. It shapes onboarding more than any design decision does.
- [Multi-architecture image](https://nerdy.pro/glossary#multi-arch-image): A single image tag that resolves to different binaries per CPU architecture — linux/amd64 and linux/arm64 are the common pair — so the same docker pull works unchanged on Intel/AMD servers and Apple Silicon laptops.
- [Multi-tenancy](https://nerdy.pro/glossary#multi-tenancy): One deployment serving many customers, each seeing only its own data, configuration and enabled features because tenant context is resolved per request. It is what makes a fleet of branded apps one product instead of many forks.
- [MVP](https://nerdy.pro/glossary#mvp): The smallest version of a product that can go in front of real users and still answer the question you built it to answer. A decision about scope, not about quality — an MVP still has to work.
- [OAuth](https://nerdy.pro/glossary#oauth): The standard behind Sign in with Apple, Google and the rest: the user authorises your app at a provider they already trust, and your app receives a token instead of their password. Nobody invents a new credential and you never store one.
- [Object storage](https://nerdy.pro/glossary#object-storage): Storage that holds a whole file under a key rather than in a filesystem tree — Amazon S3 and the many services that speak its API. Cheap, effectively unlimited, and the usual home for raw events, backups and media: written once, read rarely, kept forever.
- [PCI-DSS](https://nerdy.pro/glossary#pci-dss): The card industry security standard binding anyone who stores, processes or transmits card data. Most apps stay out of its scope on purpose, by handing card entry to a certified payment provider instead.
- [Platform channels](https://nerdy.pro/glossary#platform-channels): The bridge a Flutter app uses to call native iOS and Android code — Keychain and Keystore, biometrics, payment sheets, any SDK without a Dart package. Routine work but real work, and the first place an engineer who never left Dart will stall.
- [Post-quantum cryptography](https://nerdy.pro/glossary#post-quantum-cryptography): Encryption algorithms built to stay secure against a future quantum computer, now standardized by NIST. The migration is urgent ahead of the hardware because traffic captured today can be decrypted once such a machine exists.
- [Product-market fit](https://nerdy.pro/glossary#product-market-fit): The point at which a product has demonstrably found people who want it — they use it, come back, and pay. Before it, engineering answers a question; after it, engineering answers demand.
- [Prompt injection](https://nerdy.pro/glossary#prompt-injection): An attack where text supplied by a user is read by a language model as instructions rather than as data, steering it past its own rules. The LLM-era sibling of SQL injection, and it appears wherever user input is concatenated into a prompt.
- [Pub/Sub](https://nerdy.pro/glossary#pub-sub): A messaging pattern where a producer publishes an event and any number of consumers read it independently, with a broker in between. The producer never waits for them, which is how a request path stays fast while slower work happens behind it.
- [Rate limiting](https://nerdy.pro/glossary#rate-limiting): A cap on how many requests one caller may make in a given window. It is what stops a single enthusiastic user, a scraper or a bot from spending a month of paid API budget in an afternoon, and it has to live on your side of the integration.
- [REST](https://nerdy.pro/glossary#rest): The conventional style for HTTP APIs: a URL names a resource and the HTTP verb says what to do with it. The default way an app talks to a backend, and what most third-party integrations expect to find.
- [SaaS](https://nerdy.pro/glossary#saas): Software sold as an ongoing subscription to a hosted product rather than as a one-off license the customer installs and runs. The vendor operates the servers, ships updates continuously, and bills per seat or per usage.
- [Server-Sent Events](https://nerdy.pro/glossary#server-sent-events): A one-way stream from server to client over an ordinary HTTP connection. Simpler than a WebSocket and enough wherever only the server has something to say — a progress feed, an AI response arriving token by token.
- [Server-side rendering](https://nerdy.pro/glossary#server-side-rendering): Building a page as finished HTML on the server, so the first response already carries the content, headings, meta tags and structured data. Crawlers, link previews and slow devices read it without running JavaScript.
- [Skia](https://nerdy.pro/glossary#skia): The open-source 2D graphics library from Google that draws Chrome, Android and — until Impeller — every Flutter frame. It renders to PDF as well as to a screen, which is what print-to-PDF in Chrome is doing.
- [SOC 2](https://nerdy.pro/glossary#soc-2): An external auditor report on how an organisation handles customer data — security, availability, confidentiality — rather than a certificate you buy. Enterprise buyers ask for it, and it constrains architecture long before the audit itself does.
- [Staff augmentation](https://nerdy.pro/glossary#staff-augmentation): A hiring model where engineers from an outside partner join your team and work under your management — in your repository, your sprints, your process — instead of delivering a project of their own. You buy capacity; the code and the context stay with you.
- [Staged rollout](https://nerdy.pro/glossary#staged-rollout): Releasing a build to a small percentage of users first and widening only once the crash-free rate holds. A bad build caught at ten percent is a bad afternoon; the same build at a hundred percent is a bad week.
- [State management](https://nerdy.pro/glossary#state-management): How an app decides where a value lives, who is allowed to change it, and which parts of the screen redraw when it does. In Flutter the choice between Riverpod, BLoC and Provider is among the first architectural decisions and the hardest to revisit.
- [Time to market](https://nerdy.pro/glossary#time-to-market): How long it takes to get a product from decision to real users. Most stack and scope arguments are really arguments about this number, because every week saved is a week of revenue, feedback and competitive position.
- [TLS](https://nerdy.pro/glossary#tls): The encryption layer underneath HTTPS. It proves the server is who its certificate says, agrees a fresh key for the session, and encrypts everything after that — so the network in between sees ciphertext it cannot quietly alter.
- [Total cost of ownership](https://nerdy.pro/glossary#total-cost-of-ownership): What a product costs across its whole life rather than to build once: maintenance, upgrades, annual OS and store migrations, and the second team you staff to keep two codebases in step. Usually larger than the build quote, and almost never inside it.
- [WebRTC](https://nerdy.pro/glossary#webrtc): The browser and mobile standard for sending audio, video and data directly between two devices, with servers involved only in introducing them to each other. It is what an in-app video call is built on when it is not a rented SDK.
- [WebSocket](https://nerdy.pro/glossary#websocket): A protocol that holds one connection open between client and server so either side can send at any moment, instead of the client asking over and over. What live prices, chat and presence indicators run on.
- [White-label](https://nerdy.pro/glossary/white-label): One product shipped under many brands. A white-label mobile platform builds each client a store-ready app with its own name, design and content from a single shared codebase, instead of forking the project per customer.
- [XMPP](https://nerdy.pro/glossary#xmpp): An open, federated messaging protocol, and the long-standing alternative to writing a chat backend or renting one. It extends to presence, typing indicators and file transfer, and it is old enough that every platform has a mature client library.
