The verdict
Use Prayvine if you are a mission worker whose supporters read your newsletter and never tell you they prayed - the one-tap confirmation loop is the whole product and it works without your partners creating accounts. Skip it if you need push notifications, SMS, two-factor authentication, or an end-to-end encrypted channel for genuinely dangerous field information, because Prayvine documents none of those.

The listing that points here gives Prayvine's home page as pbc.org/team/ian-and-kim-hsu. That is not the product. It is a missionary support profile at Peninsula Bible Church in Palo Alto, California, for Ian and Kim Hsu - the couple who founded Prayvine and whom that church helps send. The product lives at prayvine.org, it is live, and the underlying listing description is broadly accurate: Prayvine is a free nonprofit prayer platform for missionaries and their supporters. The one word to strike is "app." Prayvine is a website that can be installed to a phone home screen, and there is no Prayvine listing in Apple's App Store.
What it does is narrow. A mission worker creates a prayer team, adds supporters by hand or imports them from Google Contacts or Mailchimp, and sends a short prayer request. Supporters receive it by email and tap to say they are praying. The sender is then told who prayed. Partners need no account to do that, which removes the biggest source of friction in tools like this. The home page shows Cru, InterVarsity, Food for the Hungry and Servant Partners, and claims Prayvine is "Serving thousands of mission workers and organizations" without giving a figure.
The finances are unusually open. Prayvine is a 501(c)(3) public charity in Orlando, Florida, EIN 46-4302136, granted exempt status in June 2014, and it links its own Form 990s. Those filings show a small, real operation: revenue of $201,040 against expenses of $192,189 in fiscal 2024, across twelve consecutive filing years going back to fiscal 2013. Over those years the organization reports roughly $1.94 million raised and $1.74 million spent. This is a two-founder ministry running software on donations, and it says so.
The gap is documentation rather than intent. Prayvine's help centre article "Is Prayvine a mobile app?" answers "You can download a Prayvine app to iPhones and Android devices" and links two videos. No App Store or Google Play listing exists. What the videos walk through is installing the site as a web app; prayvine.org ships a service worker, an install prompt script and a manifest with a standalone display mode. The capability is real. The wording is not, and for a product carrying confidential prayer requests out of sensitive countries, precision about what you are installing matters.
✓ The good
- Genuinely free with no paid tier - Prayvine states it is "100% donor funded," charges nothing to mission workers or supporters, and takes no fee on donations routed through platform links.
- Supporters do not need accounts - a partner can receive a request and confirm they prayed without registering, the difference between a tool people use and one they ignore. Accounts are only required to record voice prayers or send a reply.
- The confirmation loop is the product - senders see who prayed rather than guessing, the specific newsletter failure Prayvine exists to fix.
- Full financial transparency - Prayvine publishes its EIN and links Form 990 filings for eight years, including years where expenses exceeded revenue. Very few Christian software products publish anything comparable.
- No advertising and no data sale, stated in writing - the financial model article says "You will never see paid ad placements on Prayvine" and "Prayvine will never sell or share user data to generate revenue."
- Content hygiene aimed at field workers - photo metadata including GPS coordinates and timestamps is stripped, uploaded files are renamed to random characters, and content is blocked from Google, Bing, Baidu and Yandex indexing.
- Compartmentalised by design - team members cannot see each other or each other's messages; every thread is one-to-one with the mission worker, so one compromised partner account does not expose the team.
✗ Watch out
- The help centre says you can download an app to iPhone and Android - no Apple App Store or Google Play listing exists. What is actually offered is an installable web app, and the article never uses the words browser, home screen, App Store or Google Play.
- Notifications are email only - the help centre states plainly that "Prayvine currently sends prayer request notifications through email." There are no push notifications and no SMS, so a real-time prayer request is only as real-time as the recipient's inbox.
- Encryption is transit-only - the security article says content "is always encrypted through HTTPS" and the privacy policy says the same. Neither claims end-to-end encryption, and neither makes any claim about encryption at rest.
- No two-factor authentication documented anywhere - the entire Passwords section of the help centre holds one article, on resetting a forgotten password. No password complexity requirement is published either.
- Prayvine admits it cannot stop forwarding - the security article states it cannot prevent partners from forwarding prayer request emails and advises inviting only people you trust. In hostile contexts the mitigation is entirely social.
- No age minimum and no GDPR or CCPA language - the terms only require that you be "of legal age to form a binding contract," the privacy policy does not address children, and neither names GDPR or CCPA despite a user base scattered across Europe and beyond.
Best for
- Field missionaries with a supporter list who never hear back
- Sending organizations wanting a free prayer channel for staff
- Support-raising coaches teaching short, frequent updates
- Donors and boards who want to read the ministry's Form 990
Avoid if
- You need push or SMS delivery rather than email
- You require end-to-end encryption for high-risk field data
- You want two-factor authentication on a sensitive account
- You are looking for a personal daily prayer-list app
What Prayvine is
Prayvine is a browser-based prayer request platform for mission workers, run by a small nonprofit rather than a software company. A missionary creates a prayer team, populates it with supporters, and sends short prayer requests with a photo or video. Supporters get an email, tap once to confirm they are praying, and the sender is notified. It is not a devotional app or a personal prayer-list manager.
It is positioned alongside newsletters rather than against them. Prayvine's help centre says some workers use it as a real-time prayer layer on top of email newsletters, printed letters and Facebook groups, while others replace the newsletter outright. It does not attempt bulk email design, donation processing or contact management, and makes no claim to.
The confirmation loop, not the broadcast
Almost every tool a missionary already has can send an update. Mailchimp sends it prettier. What none of them do is close the loop back to the sender, and that is the only thing Prayvine is for. When a supporter taps to say they prayed, the mission worker is told - by name. Prayvine's founder, writing on a mission agency blog, reported confirmations from more than ten percent of his mailing list, many with a personal note attached.
That choice explains the rest of the product. Partners do not need accounts, because requiring one would collapse the response rate the product depends on. Requests are meant to be short. Threads are one-to-one rather than a group feed, so nobody performs prayer for an audience. The trade-off is that Prayvine is thin everywhere else: no push, no SMS, no group discussion, no analytics dashboard, no scheduling. One mechanism, executed narrowly, given away.
Prayer teams and how people get in
A worker can run more than one prayer team and a team can have more than one owner, which covers married couples and field teams sharing a supporter base. Supporters are added one email at a time, imported from Google Contacts or Mailchimp over OAuth, uploaded through a contact importer, or brought in with a shareable join link the owner approves. The owner can change a partner's email address, remove a partner, resubscribe someone who unsubscribed, and export the list to a spreadsheet.
Prayvine's security article is specific about the boundary: the only way to join a prayer team is for the owner to add, import or approve you. There is no user directory, no discovery feature, and nothing is indexed by search engines. Team members also cannot see one another - every conversation is between the owner and a single partner - so a team is not a group chat and never becomes one.
Sending a request, and what arrives
A request is composed on the web, can carry a photo or a video, and goes out by email. Prayvine's founder has publicly recommended a "1 photo / 1 paragraph" format, which matches a platform designed around a tap rather than a read. Supporters can respond with a one-tap confirmation without an account; recording a voice prayer or writing a reply requires them to register. Owners can also send a private one-to-one message to a single partner outside the broadcast.
Delivery is the weak link and Prayvine does not hide it. The help centre says notifications are sent through email, full stop - no push, no SMS. That means a request marked urgent competes with every other message in a supporter's inbox, which is precisely the problem Prayvine's own marketing describes newsletters as having. The platform improves on the newsletter by measuring the response, not by escaping the inbox.
Security posture for sensitive fields
Prayvine handles the kind of content that gets people deported. Its published measures are real but modest: HTTPS in transit, login required to view requests, invitation-only teams, no search indexing, GPS and timestamp metadata stripped from photos, uploaded files renamed to random characters. The privacy policy names its processors - ZeroBounce for email validation, csvbox.io in a mode it says stores nothing server-side, Google APIs under Google's Limited Use terms, and Mailchimp for contact access.
What is absent matters as much. No end-to-end encryption is claimed. No encryption at rest is claimed. No two-factor authentication appears anywhere in the help centre, and the privacy policy carries the standard admission that no internet transmission is completely secure. Prayvine compensates with advice rather than engineering: use a VPN on public wifi, use a password manager, use initials or aliases instead of real names, blur faces in photos, follow your organization's security policy.
Pricing
Free
Free
Every feature. Multiple prayer teams, multiple team owners, contact import from Google Contacts and Mailchimp, join links, prayer requests with photo and video, private one-to-one messages, voice prayers, partner export to spreadsheet, custom organization logo. Funded by donations to Prayvine, a 501(c)(3) charity that reported $192,189 in expenses in fiscal 2024. Prayvine states that "Every product feature currently available ... is intended to be free forever."
Voluntary donation
Any amount, tax-deductible
Not a tier and not a paywall. Prayvine says it approaches active prayer team owners twice a year, that "donations are strictly voluntary," and that it does not ask the mission worker's own partners for money at all. It takes no fee on donations supporters send through platform links. The one caveat Prayvine publishes: features such as text messaging "have different economies of scale," and it lacks the data to guarantee those would be free.
There is one price and it is zero. Prayvine states that it is "100% donor funded" and that, like the mission workers it serves, it raises support to operate. Nothing is metered, no feature sits behind a paywall, and the help centre answer on cost is four lines long.
The 990s show what free costs. Prayvine reported $201,040 in total revenue and $192,189 in total expenses for fiscal 2024, and $221,250 against $183,363 for fiscal 2023. Taking the site's own unquantified claim of "thousands of mission workers" at a conservative two thousand, fiscal 2024 expenses work out to roughly $96 per mission worker per year that somebody other than the mission worker paid.
The filings also show the risk in the model. Expenses exceeded revenue in fiscal 2022 by $100,763 and in fiscal 2020 by $125,490, and fiscal 2024 revenue of $201,040 is under half the $420,051 reported for fiscal 2021. A donor-funded free platform is only as durable as its donor base, and Prayvine publishes enough to let you see the swings rather than hiding them.
Prayvine is careful about the word forever. It says every feature currently available is intended to be free forever, then notes that some capabilities - text messaging is the example given - "have different economies of scale" and that it lacks the data to promise those would be free. That is an honest hedge, and the clearest signal that SMS is on the roadmap and may not be included.
Where Prayvine falls behind
No app in either store, despite the help centre saying otherwise. The article "Is Prayvine a mobile app?" answers that you can download a Prayvine app to iPhones and Android devices and links two videos. There is no Prayvine listing in the Apple App Store and none on Google Play. What the videos demonstrate is installing the website as a web app, which prayvine.org supports properly - service worker, install prompt, standalone manifest. Competent engineering, misleading documentation, and the article was last modified in July 2026.
Email is the only delivery channel. PrayerMate, Echo Prayer and PRAYR Community all reach a phone through push. Prayvine markets real-time prayer mobilisation and then routes it through the medium it criticises newsletters for using. Text messaging is named in Prayvine's own financial model article as a feature with different economics, which is an admission that it does not exist yet and may eventually cost money.
Authentication is thin for the sensitivity of the data. A prayer request from a worker in a closed country can contain names, locations and plans. Prayvine requires a password and stops there: one help article on password recovery, no documented complexity rules, no two-factor option, no session management guidance, no screenshot or forwarding controls beyond a warning that forwarding cannot be prevented.
The legal documents pull against the marketing. Prayvine says in two places that it will never sell or share user data. Its Terms of Use, updated 1 May 2026, simultaneously grant Prayvine a "perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute" user content - qualified as "for the sole purpose of enabling Prayvine to display, distribute and promote the Services" and extended to organizations Prayvine has relationships with. Both statements sit on Prayvine's own site and both are reported here without reconciliation. Consumer-social boilerplate reads differently when the content is a confidential prayer request from a closed country.
Nothing about the platform is quantified. "Serving thousands of mission workers and organizations" is the only usage figure published, with no number attached. A claim that 68 percent of ministry partners are more likely to donate recurs across Prayvine's articles with no sample size, methodology or date. The 990s are specific; the product metrics are not.
Prayvine vs. PrayerMate vs. PRAYR Community
These three solve adjacent problems and confusing them wastes money. PrayerMate, at 4.8 on 418 App Store ratings, is an inbound tool: it organises the requests you promised to pray for, on your own phone, free with a Pro tier around $2.99 a month. Prayvine is the outbound side of the same relationship. A supporter could run both, receiving Prayvine emails and filing them in PrayerMate.
PRAYR Community, 4.9 on 18 App Store ratings, is the closest functional overlap because it also has a tap-to-say-you-prayed mechanic, but it is a private group feed where members see each other, on iOS and Android, free with a $1.99 monthly tier. Prayvine refuses the group feed: partners cannot see one another, and every thread is one-to-one with the mission worker. For a worker in a sensitive location that compartmentalisation is the point, and PRAYR's model is the wrong shape.
Echo Prayer, 4.8 on roughly 22,000 ratings and free with a tier around $4.99 a month, sits between them with shareable prayer lists for a spouse or ministry team. It has the store presence, polish and push notifications Prayvine lacks. What it does not have is Prayvine's loop - an unregistered supporter confirming by email that they prayed, across a list of several hundred donors - or Prayvine's price, which is nothing.
The bottom line
Prayvine does the one thing missionary newsletters cannot: it tells the sender who prayed. It costs nothing, publishes its tax returns, does not advertise, and does not make your supporters sign up. It is also thinner than its own documentation implies - email-only delivery, transit-only encryption, no two-factor authentication, and a help article promising an app download no store can fulfil. If your supporters read your updates in silence, install it and accept the gaps. If a leak in your field has consequences, treat it as a private mailing list with a receipt and keep the dangerous details off it.
Alternatives to Prayvine
Frequently asked questions
Is Prayvine free, and how does it stay free?
Yes, entirely. Prayvine says it is "100% donor funded" and its help centre answer on cost reads: "Prayvine is free. Prayvine is formed as a 501(c)(3) non-profit charity, and the generosity of our donors enables us make Prayvine available for free." Its Form 990 for fiscal 2024 reports $201,040 in revenue and $192,189 in expenses. Prayvine asks active prayer team owners for a voluntary donation twice a year and does not ask their supporters at all.
Is there a Prayvine app for iPhone or Android?
Not in either store. Prayvine's help centre article says "You can download a Prayvine app to iPhones and Android devices," but there is no Prayvine listing in the Apple App Store and none on Google Play. Prayvine is a website that can be installed to a phone home screen as a web app - it ships a service worker, an install prompt and a standalone manifest - and the two videos in that article walk through that installation. You get an icon that opens full screen, not a native app.
Do my prayer partners need to create an account?
No, not to receive prayer requests or to tell you they are praying - which is the main reason response rates on Prayvine hold up. An account is required in two cases the help centre names: recording a voice prayer, and sending you a written reply. Everything else works from the email.
How secure is Prayvine for workers in sensitive countries?
Moderately, and Prayvine is candid about the limits. It encrypts in transit over HTTPS, requires a login to view requests, admits people only when the owner adds or approves them, blocks search engine indexing, strips GPS and timestamp metadata from photos, and renames uploaded files to random characters. It does not claim end-to-end encryption or encryption at rest, and documents no two-factor authentication. It states outright that it cannot prevent partners from forwarding prayer request emails, and recommends aliases instead of real names and blurring faces in photos.
Does Prayvine have a privacy policy, and what does it cover?
Yes, last updated 1 May 2026. It discloses collecting name, username, telephone number and email at signup, contact details for the partners you add, anonymised usage analytics, cookies and web beacons. It names ZeroBounce, csvbox.io, Google APIs and Mailchimp as third parties, states that personal information and content will never be sold to advertisers, and lets you delete content and your account on request while retaining archived copies where law or fraud prevention requires. Two gaps: it does not address children or set a minimum age, and it never mentions GDPR or CCPA.
Does it replace my email newsletter?
Prayvine says that depends on you. Its help centre states that many workers use it alongside email or printed newsletters and Facebook groups, while others use it instead of a newsletter. It is not built for newsletter design, list segmentation or donation processing, so if your newsletter does those jobs you will still need the tool that does them.
Who is behind Prayvine and how long has it existed?
Ian and Kim Hsu, based in Orlando, Florida. Ian previously led digital engagement strategy at Stanford University and Kim was on staff with CityTeam Ministries in San Jose; Ian is listed as founder and also authors the help centre articles. Prayvine does not publish a product launch date, but the nonprofit received its IRS 501(c)(3) ruling in June 2014 and its earliest Form 990 covers fiscal 2013, so it is over a decade old. Its stated mission is "to fuse the power of prayer with the power of technology to facilitate God's work in the world."
