privacy policy

who this covers

this policy covers the Lessons! app for iOS, made by Bang Average Software. it applies to everything the app does. there are no surprises further down - this page exists so you can check that for yourself.

what the app stores, and where

lessons! is a planner for people who teach movement classes - aerial, pilates and the like - so it holds the things you put into it:

• your timetable - your classes, when they are, how long they run, where, and any notes you add
• your lesson plans - warm-up, main content, cool-down, and your own private notes
• the categories you set up - your disciplines, class types, levels and the studios or organisations you teach for
• whether a class was taught, covered by someone else, or cancelled
• your name, if you give one during setup, so the app can greet you properly
• a pointer to each photo or video you attach to a plan, plus a small thumbnail of it (see below - the media itself stays in Photos)

all of it is stored only on your device. the app never uploads it, syncs it to a server, or transmits it anywhere - not to me, not to anyone. there is no server to send it to. the single exception is when you deliberately share a plan yourself, which is covered below.

it is worth saying plainly: i, the developer, cannot see any of it. no one can, unless they are holding your unlocked phone.

your photos and videos

this is the part worth understanding properly, because it is the bit that is unusual.

when you attach a clip to a lesson plan, the app does not copy it. it stores a reference - a note of which item in your photo library you picked - plus a small thumbnail so the grid draws quickly. your original video stays exactly where it was, in Photos, at full quality, already backed up by whatever backs your phone up.

what follows from that:

• choosing a photo or video needs no permission at all. the picker iOS shows you runs outside the app; it hands back only what you picked
• permission is only asked for when the app needs to open an original - previewing a clip full screen, or sending one. until then the thumbnails do the work
• when it does ask, the app requests read and write access. this is not a typo and it is not the app being greedy: iOS offers only "add photos" or "read and write", with no read-only option. lessons! only ever reads. it never adds, edits or deletes anything in your photo library
• removing an attachment removes the pointer, not the clip. deleting a plan, or the whole app, never touches anything in Photos
• because the media is only referenced, an attachment can go missing - if you delete the original from Photos, the app shows it as no longer in your library rather than pretending it still has it

nothing about any of this involves a server. the app does not upload your media, scan it, or analyse it.

what the app does not do

• no accounts - there is nothing to sign up for and no login
• no analytics - the app doesn't measure how you use it
• no tracking - no advertising identifiers, no profiles, nothing
• no third-party SDKs - no outside code libraries that phone home
• no ads
• no data collection of any kind by the developer - i receive precisely nothing from your copy of the app

the app makes no network requests of its own at all. the only traffic it can cause is Apple's own: the App Store, if you tap the tip jar, and iCloud Photos fetching one of your clips back down to the phone if it isn't stored locally. both are between you and Apple, and neither passes through me.

sharing a plan

the app can send a plan onwards - most people use this to put the week's sequence into a class group chat. this is the one moment your information can leave the phone, so it is worth being precise:

• you choose what goes. the share composer has two separate sets of ticks: which clips are included, and which parts of the plan travel with them. your notes are off by default, because that's where the private observations tend to live
• everything is assembled on your device. any videos you include are exported from your photo library into the app's own temporary storage, on the phone, and the app makes no network requests to do it
• once the material exists, the app hands it to the standard iOS share sheet and steps out of the way. where it goes next is entirely your decision: a message, an email, Files, AirDrop
• if you send it somewhere, that destination's own privacy terms apply to the copy you sent - a message you put in a group chat is in that group chat, governed by whoever runs it, and i have no involvement in or sight of it
• the temporary copies the app made are cleared up afterwards, and the app keeps no record of what you shared or where it went

put simply: sharing exists so a plan is yours to send, not so it can travel without you asking.

tips

the app has an optional tip jar. tips are one-off purchases processed entirely by Apple's In-App Purchase system. i never see your payment details - Apple handles the whole transaction and simply tells the app a tip was made, so it can say thank you. the app remembers, on the device only, that you tipped, so it can stop asking. Apple's own privacy policy covers the payment.

deleting your data

delete the app and everything it stored is deleted with it. that's it - there's no account to close, no request form, no thirty-day retention window, because there was never a copy anywhere else.

two things worth knowing. if you use iCloud or computer backups, your phone's backup may include the app's data as part of backing up your whole device. that backup belongs to you and is governed by Apple's terms - the app itself never puts data anywhere.

and your photos and videos are not the app's to delete. they were always yours, sitting in Photos; removing lessons! leaves every one of them exactly where it was.

children

lessons! is a tool for the person teaching the class, not the people in it. it isn't aimed at children, it holds nothing about your students, and it collects nothing from anyone regardless of age.

changes to this policy

if the way the app handles your data ever changes, this policy will be updated before that change reaches you, and the date at the top will change with it. syncing your own data between your own devices with iCloud is planned for a future version; if and when that arrives, this page will say so plainly first.
