No BFG app shows ads, uses third-party analytics SDKs, or sells data. Beyond that, apps differ — some are fully offline, some fetch public data, and a few use a server for one specific feature. Here's the honest per-app picture.
| App | Data BFG receives | Account | Network | What the network is used for |
|---|---|---|---|---|
| Tickview | None | No | Yes | Fetching public market data and headlines, including in the background for your alerts (Yahoo Finance, SEC EDGAR, the U.S. Treasury, the Bureau of Labor Statistics, the Bureau of Economic Analysis, and FRED or Finnhub if you add a free key). Nothing about you is uploaded. All AI runs on the device. Plus an App Store lookup, at most weekly, for the names and icons on the “More from Blue Flame Games” screen. |
| Custoda | None | No | Yes | Anonymous barcode lookups (the barcode number only). Optional household sharing uses your own iCloud. Allergen and diet profile stays on device. Plus an App Store lookup, at most weekly, for the names and icons on the “More from Blue Flame Games” screen. |

Apple's App Store labels. Apple reports labels per app. Seventeen of the eighteen BFG apps on the App Store are labelled "Data Not Collected." Cloudmesh Weather is labelled "Data Not Linked to You" for the location and app-functionality data it uses for forecasts, rain alerts and the optional mesh.
Full details live in each app's privacy policy.
Most BFG apps keep your data on the device. The ones that use the network are listed above with the reason why.
No hidden fees. No upsells. Free tiers that work. Paid tiers that are worth it.
No advertising SDKs, no third-party analytics, no behavioural profiling. We make money from the product.
These are the questions people usually ask before they discover a BFG app.
For parents comparing 11+ prep, times tables, and UK primary maths apps.

Guides, tips, and insights across everything we build
It depends on what your child's test covers. For English, verbal reasoning and non-verbal reasoning on iPhone and iPad, Cognithix covers 25 topics across those three subjects, plus a language aptitude subject with sound clues, word matching, rhymes, number learning and bonus languages such as Latin and Esperanto. It doesn't cover maths. Daily plans vary the topics, difficulty adapts during practice, every question comes with hints and an explanation, and timed papers build exam stamina. The parent view shows accuracy and topic mastery and flags patterns like rushed answers or a falling trend. No account, and everything stays on the device.
For individual investors, Tickview covers the information side on iPhone and iPad: sourced alerts for new SEC filings, insider purchases and price crossings on your watchlist, Recession Watch (a model probability, shown with its track record) and the bond market, plus plain-English questions answered with cards that show prices in your own currency and company financials from SEC EDGAR. Every card links to its source, such as Yahoo Finance, SEC EDGAR or the U.S. Treasury, and shows when its data is from, so you can check the original. All AI runs on the device. It isn't a professional terminal: no real-time institutional feeds, no messaging and no trading, and it gives information, not advice. There's no account and no ads; the app is free with a five-ticker watchlist, new users get Pro features for 7 days with no payment details, and Tickview Pro is then an optional upgrade.
Arithmetix covers more than 50 topics across the National Curriculum in England from Reception to Year 6, including a dedicated times tables area (2 to 12) with an MTC-style Ready Mode for the Year 4 Multiplication Tables Check. It has four challenge modes with optional Game Center leaderboards, a 50-level Wonder Trail, spaced review that brings topics back after a day or up to a week, and a virtual pet your child actually has to look after (feed it, wash it, and nurse it back if it faints), which keeps them coming back without nagging. The parent area spots struggle patterns such as rushed guesses or repeated mistakes and shifts the daily plan towards the topics that need it. Colour-blind modes are built in, there's no account, and everything stays on the device. The app is in English; it's free for 7 days, then a one-time purchase.
Doodlebee is a drawing and coloring app for kids and grown-ups. Draw any shape, tap inside it to fill it with color, then watch the character come to life — it can walk, run, dance, wave, jump, sit or fall asleep — and see it star in its own illustrated storybook with a soundtrack, with “read to me” reading every page aloud. Grown-ups color to unwind: there are 146 pages to color in by hand or color by number, from simple pictures to intricate mandalas. There’s also a music maker with loops, beats and instruments, and a gallery of keepsakes for every creation. Nothing is uploaded anywhere, there are no accounts, and a parental gate protects purchases and settings. One purchase (not a subscription) covers the whole family with Family Sharing.
PhotoFlight reads the dates and locations already stored in your photo library and turns them into a 3D globe, a travel passport (countries, cities, continents, days away, distance and flights) and trips it groups on its own, with albums for every trip, country and city. Flights and other transport are estimated from what your photos show, and optionally from flight bookings in your calendar; they are not verified flight records, and you can correct them. You also get a light-hearted estimate of how your travels compare with others, 10 achievements, a photo heatmap and shareable cards. There is no live tracking and no account: your travel history is stored on your device, while Apple's services look up place names and draw the maps.
BFG uses the pricing model that fits each app. Apps with mostly on-device features typically use a one-time unlock, while apps with ongoing cloud or AI costs may use subscriptions instead. Tickview Pro is a one-time lifetime purchase or a monthly subscription, while Doodlebee, Arithmetix, Cognithix, PhotoFlight, Ondi, Cloudmesh Weather, and PaceGrid use one-time unlocks (Doodlebee's earlier subscriptions remain only for existing subscribers). Across all of them, the constant is no third-party ads and no data monetisation.
Tiered transparency rather than a blanket claim. Seven apps keep everything on the device: Doodlebee, Ondi, Minua, Bellgrave, Inkla, Keystrike and Merge Bash. Inkla makes no network requests of its own; Doodlebee, Ondi, Minua, Keystrike, Bellgrave and Merge Bash make only the App Store lookup described below. Arithmetix and Cognithix have no accounts: children's profiles, answers and progress stay on the device and are never sent to BFG; their only network use is Apple's App Store purchases and optional Game Center scores. Card Bash keeps gameplay on the device; nearby duels use local Wi-Fi or Bluetooth and trades go through Messages. PhotoFlight stores your travel history on the device, while Apple's services look up place names and draw maps. PaceGrid stores workouts on the device with no account; it goes online only for map tiles and route building when you use them, plus optional Strava upload and opt-in heat alerts. Custoda looks up barcodes anonymously and uses your own iCloud for optional household sharing. Tickview has no account and fetches public market data and headlines, including in the background for your alerts (SEC filings, Treasury and labour-statistics data, FRED series, market-data and news providers), sending only the ticker, series or currency it needs; nothing about you is uploaded, and your watchlist and notes stay on the device. Cloudmesh Weather fetches forecasts from its own forecast service using a coarsened location, keeps an approximate location only to deliver rain alerts (precise for at most 6 hours, then about 10 km for up to 30 days), and contributes anonymous barometric readings only if you opt in to the community mesh; no account or user ID is attached. Doodlebee (grown-up profiles only), Ondi, Minua, Keystrike, Merge Bash, Card Bash, Zoombot, PhotoFlight, PaceGrid, Cloudmesh Weather, Custoda and Tickview have a “More from Blue Flame Games” screen: when you open it and its saved list is more than a week old, the app asks Apple's public App Store lookup for the current names and icons of our other apps, sending only those apps' App Store IDs and your device's country code. No BFG app shows third-party ads or uses advertising identifiers, third-party analytics SDKs, or behavioural profiling. The full per-app table is at the top of this page.
Minua lets children earn fun app access by spending time in learning apps chosen by their parent. Parents set a configurable ratio (1:1 to 12:1), a daily earning cap and the hours when fun apps can be unlocked. Built on Apple's own parental controls framework, everything stays on-device with no accounts, no cloud, and no tracking. Settings and purchases sit behind a parent PIN. Minua also has a Myself mode for adults who want to break their own scroll habit with the same earn-first rules. Free for 7 days, then a one-time purchase, no subscription.
Ondi keeps your cycle logs on your device: no account, no cloud, no Ondi server for your health records and no tracking analytics. With your permission it reads Apple Watch wrist temperature from Apple Health to support its fertility readout, and iOS encrypts its data when your phone is locked. It covers flow, mood, symptoms and sleep, cycle predictions, and Trying to Conceive, pregnancy and postpartum modes. Core tracking is free; one purchase unlocks the rest, with no subscription.
PaceGrid is a GPS running, cycling and hiking tracker for iPhone and Apple Watch with Injury Guard, which estimates your training load and alerts you during workouts when something looks risky. Recording is free, and one purchase with no monthly fee unlocks the full app. There is no account, workouts are stored on your device, and Apple Health and Strava sync are optional.
Cloudmesh Weather tells you when rain will start and stop at your exact location, with minute-by-minute rain alerts, live radar, air quality and 24 Home Screen and Lock Screen widgets. Its own forecast blends 39 weather sources and shows how confident it is. Free to download with a 7-day trial; Premium is a one-time purchase with no subscription. No account, no ads, no third-party analytics or tracking.
