Haven · IVF Companion App

Private by design.
Present by choice.

An IVF companion built for the person going through treatment.

IVF is one of the most detailed, emotionally demanding experiences a person can go through. It asks you to track medications, attend frequent appointments, process daily updates from the lab, and hold an enormous amount of uncertainty — often in private, often alone. Haven was built to hold that detail alongside you.

IVF generates more private health data than almost anything else

Medication logs. Hormone levels. Follicle counts. Fertilisation updates. Embryo development reports. Cost breakdowns. And threaded through all of it — a private emotional record of one of the most significant things a person can experience.

Most apps that exist for this purpose are built around connectivity — syncing to the cloud, sharing with a care team, storing data on servers they control. The implicit trade is: convenience in exchange for surrendering control of the most sensitive health information you'll ever generate.

Haven doesn't make that trade. Your data stays on your device. There is no account to create, no server storing your cycle history, and nothing that can be breached, subpoenaed, or shared without your knowledge.

Privacy in Haven is architectural — not a policy promise. The server cannot share what it never holds.

Nothing to breach. Nothing to subpoena.

Zero-knowledge architecture

Haven's design means your health data never leaves your device — not to Haven's servers, not to any third party. This isn't a privacy setting you have to find. It's how Haven is built.

No account required
You don't create a username or give Haven an email address. There is no profile to data-mine and no identity to link to your treatment.
Data stored only on your device
Medications, cycle history, journal entries, appointment records — all encrypted locally. Deleting the app permanently erases everything. There is no backup to retrieve from.
No tracking, no analytics
Haven does not track how you use the app, does not send usage data to third parties, and does not serve advertising. Nothing about your behaviour inside Haven is observed.
Chosen sharing, not assumed
If you want to invite a partner or trusted person into your circle, Haven supports that — on your terms. You control what they see. The kill switch disconnects anyone instantly.

Everything a cycle asks of you, in one place

Haven covers the full experience of IVF treatment — from the first injection to the pregnancy test and beyond.

Cycle tracking
Every phase — preparing, stimulation, trigger, retrieval, fertilisation, transfer, the two-week wait — tracked day by day with a visual journey that shows exactly where you are. Phases advance automatically based on your dates, so the app always reflects your current moment.
Medication tracking
IVF involves multiple medications — injections, pessaries, oral tablets — often at different times of day. Haven tracks each one with dosage, timing reminders, preparation guides for injectable medications, and video instructions. Stock tracking alerts you when supplies are running low.
Appointments
Monitoring scans, blood tests, retrieval, transfer — IVF appointments arrive at short notice and stack up quickly. Haven keeps them organised and connected to your cycle phase, so you always know what's coming next.
The two-week wait
Haven's TWW mode was built specifically for the hardest phase. The orbital mark enlarges and slows. Daily grounding prompts replace the clinical interface. The app changes its register to match where you are — because the two-week wait isn't a tracking problem, it's an emotional one.
Daily check-ins and journal
A quiet space to record how you're feeling — physically and emotionally — as you move through treatment. Not a wellness tracker. A private record of the real experience. Journal entries are stored separately from clinical data and are never included in cycle exports.
Cost tracker
IVF is expensive, and the costs accumulate in ways that are hard to keep track of. Haven's cost tracker records medications, procedures, and add-ons against a budget you set, and generates a full cost breakdown at the end of each cycle.

Every path through fertility treatment is different

Haven supports the full range of fertility treatment protocols — not just standard IVF. Whether you're doing your first cycle or your fifth, whether you're at the beginning of investigations or partway through a complex protocol, Haven adapts to where you are.

IVF
Full stimulation cycle — fresh or frozen transfer
ICSI
IVF with intracytoplasmic sperm injection
FET
Frozen embryo transfer — medicated or natural
IUI
Intrauterine insemination with TWW tracking
Egg freezing
Fertility preservation — shorter phase pathway
Natural cycle
Minimal medication, monitoring-led approach

One app. Many different journeys.

There is no single story that leads someone to fertility treatment. Haven is used by people at every stage — from a first round of investigations to a fifth IVF cycle, from egg freezing at 31 to a medicated FET after a long break.

S
Sarah
Third IVF cycle · Freeze-all with PGT-A · Experienced patient
IVF PGT-A Freeze-all

Sarah has been through IVF twice before — one cancelled cycle and one negative result. She knows the process, but she's tired of keeping track of everything in a combination of the clinic's portal, a spreadsheet, and her own memory. She wants her third cycle documented properly, including her historical data from previous rounds.

Haven lets her add her previous cycles before she starts, so everything is in one place. She manages dose changes mid-stimulation, tracks multi-strength medication stock, enters per-embryo PGT-A results after biopsy, and compares her retrieval stats across all three cycles at the end.

P
Priya
Egg freezing · First time · Fertility preservation
Egg freezing First cycle

Priya isn't trying to conceive right now — she's freezing eggs to preserve her options. She's never done anything like this before, and the terminology alone feels overwhelming. She wants somewhere to read about what she's taking, track how she's feeling, and not have to explain everything to someone else.

Haven's preparation guides and medication videos walk her through each injectable before she does it for the first time. The egg freezing protocol path skips the embryo tracking and TWW phases — because for Priya, the cycle ends at retrieval. She keeps everything to herself.

M
Megan
IUI · Third cycle · Oral medication only
IUI Experienced

Megan has been through two IUI cycles — both negative. She uses Haven primarily for medication reminders and appointment management, since her protocol is relatively simple. But the two-week wait is the same emotional experience regardless of how straightforward the treatment is.

She adds her two historical cycles at setup, tracks her oral Letrozole, and uses the journal daily during the TWW — building a record of mood entries across the waiting period that she finds more useful than anything she could share with her clinic.

L
Leila
First IVF cycle · Fresh transfer · New to self-injecting
IVF Fresh transfer First cycle

Leila is doing IVF for the first time. She's never self-injected before, has never done a monitoring scan, and has never had to track hormone levels. Everything is new and the terminology is dense. She read the privacy promise on the onboarding screen carefully before she did anything else.

She uses the medication preparation guides and injection videos before each new drug. Her fresh transfer goes to a Day 3 transfer — Haven adjusts the TWW timing accordingly. She journals extensively — it's the first time she's processed the experience of IVF anywhere.

A
Aisha
Medicated FET · Four concurrent medications · Complex protocol
FET Medicated High complexity

Aisha has frozen embryos from a previous retrieval cycle and is now doing a medicated FET. Her protocol involves four simultaneous medications — oral oestrogen three times a day, daily aspirin, vaginal pessaries twice a day, and a subcutaneous injection — across three different administration routes.

Haven groups her medications by time of day on the Today screen so nothing gets missed. All four medications continue through the two-week wait, so the app keeps showing her full schedule even after transfer. She journals every day, building the most detailed mood grid of any cycle.
