About this appAI proposal
Plainroll backs up your photos and videos with encryption that happens on your device, so the service cannot view them. It is for people who want out of the big clouds but worry that a small company might run out of money and take their memories with it.
Plainroll answers that worry in the open. A public page shows what the service costs to run, what comes in from subscriptions, and how many months it can operate if no new customer joins. Figures update monthly and anyone can read them without an account.
If money gets tight, you hear early. A written shutdown promise sets aside storage and time for you to download everything in standard formats. Your photos stay ordinary files you can take anywhere.

- Why this name
- Plain for plain files and plain dealing; roll for the film roll of memories. Two ordinary words, easy to say.

PricingAI proposal
The only verified price is Apple's one-time $1,199 to $2,399 plans, which are not photo storage plans and give no guide. The tiers are a starting point to test; the material gives no storage prices.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users share albums by link with family and friends who have no account. The page shows a small Plainroll mark and a link to the public health page.
- Do they become customers?
- Viewers could become customers, since they see the same privacy case. To test: how many album viewers open the health page and sign up for the free tier, and how many then pay.
- First customers
- Privacy-minded people who already care about owning their data: self-hosting hobbyists and developers with large family photo libraries who left or are leaving big cloud providers.
- Where to reach them
- Hacker News and tech forums: Post the public health page and shutdown promise as a Show HN, and answer questions about how it works.
- Self-hosting communities: Offer a free export and import guide, with early-access invites to members who give feedback.
- First milestone
- 200 free sign-ups and 20 paying customers in 90 days, with a published health page and a tested full export.

RisksAI inference
- PlatformA PWA cannot reliably back up in the background on phones, especially iPhones. Users may need to open the app to upload, which weakens the automatic backup people expect.
- CommercialStorage costs scale with users, and the free tier may drain cash. Publishing finances also exposes weak months to the public, which could scare off customers.
- TechnicalWith keys held only by users, a lost recovery phrase means lost photos. Encrypted storage also limits search, face grouping and thumbnails.
- CommercialTrust is hard to win from a new name against large providers. Self-published figures are claims until an outside party checks them.
- RegulatoryStoring family photos, including images of children, brings content abuse duties and takedown rules that are hard to apply to encrypted content.
