I tell stories about broken people in strange worlds — crumbling lighthouses, fantasy bloodlines, and cursed call centres. Whether it’s a slow-burn thriller or an absurdist comedy, I’m drawn to the human fallout beneath the spectacle. Find out more below...

ON HOLD
On Hold is a bleakly funny, sharply observed British workplace TV comedy series set in the underfunded customer retention team at CloudConnect Telecom — a company that proudly promises “Connection You Can Count On,” and never delivers.Each episode drops us into a fluorescent-lit purgatory of motivational posters, passive-aggressive HR policies, and morale-boosting exercises that only deepen everyone’s existential dread. Here, survival means dodging wellness surveys, navigating vending machine politics, and pretending you haven’t heard Carl muttering “they’ll all cancel” under his breath for six years straight.The team are underpaid, underappreciated, and deeply over it — but somehow, they keep showing up. Sort of.

GRIDLINE PRO — PRIVACY POLICYLast updated: 5 July 2026Gridline Pro ("the app") is designed to be private by default. This policy explains what the app does and does not do with your information. In this policy, "we", "us" and "the developer" mean Harrison Davies, the developer of Gridline Pro.THE SHORT VERSIONYour solo detecting stays on your device — no accounts, no analytics, no advertising, no trackers, and nothing sold. The only time your data leaves your device is when you use the group features (Meet Now, scheduled meets and leagues): to let people on iPhone and Android share a meet by code, that meet's data syncs through our relay, where names, precise coordinates, field outlines and chat are encrypted, so they are not stored in plain text. Your solo digs never touch it.WHAT THE APP STORESAll of your data — sites, fields, landowners, permissions, equipment, finds, photos, flags, hunt sessions, signed agreements and profile details — is stored locally on your device using Apple's Core Data.If you enable iCloud, this data may also sync to your own private iCloud account using Apple CloudKit. This data lives in your iCloud and is governed by Apple's Privacy Policy. The developer of Gridline Pro has no access to it.DEVICE PERMISSIONSCamera — used only to take photos of your finds. Photos are stored with the find on your device. They are never uploaded to us.Photos — find photos you take are also saved to your own Photos library at full quality, so you keep the original. The app only adds them; it doesn't read your library.Location — used on-device to log find positions, draw field boundaries, provide compass-guided return to your flags, and support optional safety features during Meets. For solo digs your location is not sent anywhere. In a group Meet, your find and SOS positions are shared to that Meet's participants via our encrypted relay so teammates can see coverage and reach you.Motion & Fitness — used only on-device to count your steps and walking distance, shown in your session summary.Microphone — used only to record optional voice notes on a find. The recording is stored with the find on your device. It is never sent to us.Nearby Interaction & Local Network — used only to guide you to a nearby person's phone (for example, a helper or another participant in your Meet) over a direct device-to-device connection. No location or identity is sent to us or any third party.Bluetooth — used only if you connect an optional external high-precision (RTK) GPS receiver, to improve coverage accuracy. The connection is directly between your phone and that device.Face ID — used only on your device to unlock your private diggers roster (which holds other people's contact and emergency details).Calendar — used only if you choose to add a scheduled Meet to your calendar.You can revoke any permission at any time in iOS Settings.FIND IDENTIFICATIONWhen you use automatic photo identification, the app uses Apple's on-device intelligence (subject to a device's capabilities and features in your geographical location) and, where necessary, Apple's Private Cloud Compute to suggest what a find might be. Any processing that leaves your device is handled by Apple under Apple's privacy terms, which are designed so that Apple does not retain your data after the request and the developer never receives your photos or the results. These suggestions are best-guess only and are not appraisals or facts.MEETS & LEAGUESWhen you run or join a Meet or league, that Meet's shared content — your display name, the squares you are working, finds you log to the shared scoreboard, chat messages, the field outline, and (only if you raise one) an SOS alert with your location — syncs to the other people in that Meet so everyone sees the same grid. This syncs two ways: via Apple iCloud between iPhones (the developer has no access to that), and through our relay, hosted for us by Supabase acting as our data processor, so that people on iPhone AND Android can share the same Meet by code. On the relay, names, coordinates, the field outline and chat are encrypted, so they are not stored in plain text; this data is used only to run your Meet, is never used for advertising, profiling or tracking, and is never sold. We do not read your chat. (Because the encryption key is tied to the Meet's join code, this protects your data from being read at rest — it is not a claim that it is technically impossible for us to access it.)Find photos are not sent to the relay. By default, compressed photos of finds you log during a Meet are added to that Meet's shared gallery via Apple iCloud (turn off "Share my Meet finds" in Settings to keep them private — your finds still count either way); they stay within Apple's ecosystem and the developer never receives them.Once you share content into a Meet, the other participants can see and keep it, and it cannot be withdrawn from devices it has already reached — so only share what you're comfortable sharing.CHILDREN & KIDS MODEKids Mode is an optional, parent-controlled experience locked behind a parental PIN.In Kids Mode (and Under-13 mode), in-Meet chat is hidden and disabled on the device. For solo use nothing is collected; a child's finds and photos are stored on the device or the family's own iCloud exactly like any other user's, for a parent to manage. If a child takes part in a group Meet, the same Meet data described above (a display name, positions, and any chat) is shared to that Meet via the relay — so keep Under-13 mode on for any device used by a child to keep them out of chat.The app is not designed to collect personal data from children.WHAT WE DO NOT DOWe do not use analytics or crash-reporting SDKs.
We do not show ads.
We do not use third-party trackers, and we do not track you across other apps or sites.
We do not sell your data or use it for advertising or profiling.
We do not send your solo data off your device.SHARING YOU CHOOSE TO DOThe app lets you export PDF reports, CSV files, and JSON backups, and email a signed permission agreement. These exports are created on your device and are shared only if and where you choose to send them. Once you share a file, its handling is governed by the service or recipient you send it to.DELETING YOUR DATAYour on-device and iCloud data is fully in your control: deleting the app and clearing its data from your iCloud removes everything. Meet data on our relay exists only to run the Meet — a Meet stops being joinable when the organiser ends it. For any request about data held on the relay, contact us below.CHANGESIf this policy changes, the updated version will be posted here with a new "last updated" date.CONTACTQuestions about privacy: [email protected]
