Every feed, every chart and every history on the market page is free, and none of it asks for an account. Market data should be: a number that says what the world costs is not a thing to put behind a till. Nothing there is sampled, delayed or held back for paying accounts, and nothing on the rest of this page applies to it.
What is priced here is the application — the private ledger: your portfolios, your cost basis, your transactions. It is sold as a club of twenty-one thousand seats. A seat is bought once and does not expire. There are four cohorts, each larger than the one before it and priced higher — so the earlier you arrive the less you pay, and what you pay never changes afterwards. Beside the seats there is a yearly subscription, and when the last seat goes it is the only way in.
The club is open: seats and the subscription are sold inside the application, at the prices on this page. The ladder was published before the first seat was sold rather than after — a price nobody can check in advance is not a price, it is an announcement.
Free asks for no card, and the charts not even for an account. Of the two priced ways, both open exactly the same application — every feature, every chart, the same encryption. What they differ on is what happens next year.

The free days count from the day you register. After them a free account still reads, exports and deletes everything, and the alerts and plans already set keep running; adding entries and setting up anything new wait for a seat or a year. Portfolio slots are not sold with either: they are earned by inviting friends, the same way whichever way in you choose.
How many seats are gone, and which cohort is open today, is shown in the app — one counter, in one place, so the two can never disagree.
Nobody is named on this page, on purpose. Prices and feature lists move, so a table of rivals here would be out of date within a quarter, and where this site does compare by name, the page lists its sources and the date they were read. These are three properties that do not move, and what Perly does instead of each.
Paid once. The cohort you join is the price you keep.

$21 · 21 seats · seats 1–21
The first twenty-one seats, at the lowest price the club will ever ask.
$42 · 210 seats · seats 22–231
Still small enough that the seat number means something.
$105 · 2,100 seats · seats 232–2,331
Where the club stops being an inner circle and starts being a product.
$210 · 18,669 seats · seats 2,332–21,000
The last cohort, and ninety per cent of the seats. When its final seat goes, no seat is ever sold again.
A cohort closes when its seats are sold, not when a clock runs out. One that nobody buys stays open at its price for as long as that takes.
21,000 seats in all, and never one more.
At a Bitcoin price of $100,000, a founder seat costs exactly 21,000 sats. The number of cohorts, the size of the club and the price of the first ticket all land on the same number.
The subscription is on offer beside the seats from the first day, and it outlives them: when the last seat is gone it is the only way in, at the price it has today. A subscriber can still buy a seat while seats remain — the time paid for and not yet used comes off its price.
$7 a month, paid yearly
Paid once a year, on every rail.
It is what running Perly costs, with room left to keep building it. A year of subscription pays for the servers and the backups, for market data licensed for a product that charges, and for the network fees and taxes every payment carries — set so that each subscriber covers their own share rather than being carried by the next one. Against a seat it is plain arithmetic: the last seat costs 2.5 years of subscribing, paid once, so a club member is ahead from year 3.
$210 ÷ (12 × $7) = 2.5
2 × 12 × $7 = $168 < $210
3 × 12 × $7 = $252 > $210
The two are priced against each other on purpose: long enough that subscribing is a real choice, short enough that a seat is plainly the one to keep.
There are no cards. Dropping them drops the merchant of record with them, and with it the tax registrations across dozens of jurisdictions, the verification onboarding, the chargebacks and the four per cent. The price shown is the price charged.
A subscription inherits the club's own rule: your cohort is your price. Whoever subscribes at one price pays it for as long as they do not stop, and indexation reaches new subscribers only. The side effect is worth saying plainly, because it cuts both ways — stopping gives up the old price for good.
A trial is a subscription that cost nothing: the same access, the same expiry, the same screen at the end. When the 14 days are up, adding and changing entries stop, and so does setting up anything new around them — goals, plans, alerts, watched addresses. The account still reads, exports and deletes, and writing waits for a seat or a year. The demo portfolio fills every chart with eighteen months of history in one click, so 14 days is long enough to judge the product before entering a single transaction of your own.
Two things are easy to run together. Access is whether you are inside the application at all, and it is bought — by a seat or by a subscription, there is no third way. Portfolio slots are a separate axis entirely: they are earned — one for each friend you invite who confirms their e-mail, up to five; one for signing up with a friend's code; more with an unlock code — and a seat does not grant them. A member and a subscriber both start with one portfolio and widen it the same way.
Access to the application stops; your data never does. An expired account still reads, exports and deletes — its entries, its portfolios, the account itself; it only cannot add or change an entry, or set up something new around one. Taking reading away would make “your records are yours” false at precisely the moment somebody tests it. Paying restores writing at once.
There are no refunds. A payment moves in one direction: once it arrives, it is not sent back — there is no card network to reverse it and no chargeback to ask for. What stands in a refund's place is the 14 free days: the deciding happens before the money does. Nothing renews by itself either, so there is never a payment you did not start.
Access to the application lasts as long as Perly runs. If Perly ever stops, the last release is opened under a free licence and a full export of your data is guaranteed — that export already works today. Three sentences, published before the first seat was sold, because a promise this size should be checkable rather than implied.
It begins with a free account: 14 days of the whole application. Seats and the subscription are bought inside the app — nothing is charged until you choose one there.
