The brand book.

Boilerplate · October 2026

Sedonis makes apps for people who make and sell things. It is based in the UK, and each product is built for one trade and stands as its own brand. Notch gives independent clothing and product brands landed cost, stock by size and colour, and profit per drop. Turnover shows resellers on Vinted, eBay, Depop and Vestiaire their real take-home after every platform fee, and how long their cash has sat in unsold stock.

Each signs in with a Sedonis account: one sign-in, one plan, and a choice of how records are stored. Standard, the default, syncs a copy Sedonis can read. Vault, optional on every plan, encrypts records on the device before they sync. This device sends nothing. One app is free with no card, and shows the profit on every item. Pro is £6.99 a month with a 14-day trial, and adds the P&L month by month and invoicing.

One maker. Products that stand on their own.

Sedonis is the maker. Notch and Turnover are its products, and each is a brand in its own right.

The maker

Made by Sedonis

The product leadsNotch and Turnover each have their own wordmark, colours, display face and sign-in. Sedonis is the maker, credited in small type under each product.
“by sedonis”Set small under a product wordmark, at 15% of its height, in the product’s quiet ink. Never emerald, never with the Split-S, never under 11px tall. Use it on sign-in screens, footers, about panels and once in each marketing piece. Leave it off app icons, favicons and avatars.
SharedThe 120-unit grid, 45° cuts, two-piece marks, Inter for every interface, and emerald for money in.
OwnedGround, hue, action colour, display face and which corners get cut.

Sedonis: the maker.

Graphite, emerald and Bebas belong to the company, the account and the hub, not to the products. The Split-S is two chamfered halves locked on a 45° axis. It appears in four places only: the lockup, the opening intro and the hinge where the homepage seam opens into the two products, and the seal on a record.

Primary lockup on graphite. Clear space on every side: a quarter of the mark’s height.

On Paper the lockup is ink, never emerald.

ColourEmerald or ink on graphite, ink on Paper. One colour, flat, upright. Never outlined, rotated, recoloured per letter or put on a gradient.
SizesHorizontal lockup at 24px tall and up. Wordmark at 16px and up. Between 16 and 24px use the small mark alone: its heavier stroke keeps the split visible.
In running textWrite Sedonis as a plain word. The drawn wordmark belongs in the lockup, not inside sentences.

Sedonis palette.

The company palette. One graphite ground; ink and hairlines carry the page; Emerald is money in, the Sedonis mark, and its one primary action. Each product has its own palette, below.

Ground

One graphite world. The table, a sheet on it, a control on the sheet.

Emerald

Money in, in every product; the Sedonis mark; and the company’s one primary action. A product never uses emerald for its buttons.

The working line.

Sedonis’s one recurring device. A money figure never appears alone: it comes with the sum that made it, in mono, on one line. The tick at the start says whose figure it is. The result is emerald when it is money in. Illustrative figures always say “example”.

OperatorsA true minus sign (−), never a dash. Terms never break across lines; the line wraps between them.
ColourFigures in ink, labels quieter, the result in emerald for money in. A cost total stays ink.
WhereHomepage, about, plans, share cards, posts and tools: wherever Sedonis states a figure.

Notch: the studio.

For independent clothing and product brands. Pattern paper, a cutting table and a rose thread. Light first, with a plum-black night mode.

Notch on its own ground, with its own action colour. Illustration of the brand, not a screen from the app.

Display facePiazzolla 700. Sentence case, 28px and up. Chiselled wedge serifs, no hairlines. Inter for every interface.
ShapeSquare corners. Buttons are cut at the top left only, like a pattern piece. The selected item takes a 45° V notch in its left edge.

IconDeep rose mark on a chalk tile with a hairline edge, cut at the top left and bottom right.

Turnover: the night shift.

For resellers on Vinted, eBay, Depop and Vestiaire. Parcel tape, a warm lamp and a price tag moving fast. Dark first, with a receipt-paper day mode.

IconCarbon mark on an amber tile, like a shipping label, on the same chamfered tile as the family.

The seal.

Every record shows where it is stored with the Split-S in one of three states. Apart and ink: a readable copy leaves the device. Locked and emerald: the record leaves as ciphertext. Locked with no sync line: nothing leaves.

Voice.

Plain, specific and honest about the fine print. The founder’s voice, not a brand voice.
